IOException break the server if client crashes or it's closed abruptly

This exception can happen when the client closes but it doesn't break the server.
If the client crashes or its closed abruptly it breaks the server. I assume it's because the read/write threads for packets get closed/stuck?

Two player simultaneously logging in crashes

Id/NameStorage in PlayerStorage needs to be switched to a ConcurrentDictionary

Double-mounts aren't working.

Issue:
The mount itself works and the owner will be able to mount it, but the 2nd player won't be able to board the mount.

Some IDs you can test this on:
50600210
50600218
50600240

Gathering/Mining

- Giving Life Skill experience
- Limits on # of harvests
- Harvesting nodes in house separate from open world

• Calculation of low to impossible is set to low * 1.3 which is wrong. Right now there's no solution available. Nexon is pepega brain

Low: 10 Imp: 13 which is correct however from 2nd tier onwards its no longer correct as seen below.
Low: 14 imp: 19 = 1.35
Low: 17 imp: 22 = 1.29
Low: 23 imp: 29 = 1.26
Low: 29 imp: 37 = 1.27

Use this app https://github.com/AngeloTadeucci/PacketToSQL to sniff shops and create the seeding SQL files.

Shops done: 40~/??

Add correct town NPCs

Currently NPCs do not correctly load in towns. Missing shops and doctors.

Enchanting

Issues:
Ophelia:

• Gives +5 levels per attempt
• Gives 10 fail-stacks per attempt, whether successful or fail
• 90% success rate per level, though not sure if it actually applies
• Levels 10-15 don't require sacrificial copies
• Materials don't get taken away after an attempt

Peachy:

• Materials don't get taken away after an attempt
• Seems like 2 attempts = +1 level

Video Example:
https://youtu.be/kvRANRZ2jxA

Parties

• Basic usage (create, leave, invite)
• Correctly update HP/Location and grey out if not on the same map
• Summon party scroll
• Vote to kick
• Enter Dungeon support and detecting dungeon to enter

World Map

• Hot spots, fishing spots, etc.
• Saving map exploration progress

Discord link invalid

I would be interested in getting more involved with the project. Unfortunately, the link to the Discord server is no longer valid. ☹

Quests

• Completing quests and giving their respective awards
• Being able to accept quests and enter hidden/instanced areas
• Handle all quest conditions

Implement badges packet

Issue:
"Badges" aren't saving once you switch characters/sign off. This is every badge in the section of your character, not just 1.

For example, pretty much all of these disappear.

Skill-tree pages aren't saved to the DB.

Issue:
The skill-trees in-game aren't saved once logging out of the character. I'm assuming this is DB-related.

Video Example:
https://youtu.be/AwI6fmh5vNs

Housing

• House triggers
• House commands
  • Survey
  • HostBall
  • Roll
  • RandomUser
  • HostGravity
  • HostAlarm
  • Card
• Loading player houses from account
• Block placement, properties (teleporters) etc.
• Daily design box
• Star architect score
• Housing Settings (disable skill use)
• Saving and loading of house designs
• Life skills blocks
• Interactable furniture
• Portal cubes
• Unlock blocks trough trophies/others

Moving with a mount doesn't update the player position correctly.

Although the player will move for others properly, the player's coords do not change, they stay the same as where the player got on the mount.
(ie. Dropping items will fall where you got on the mount, /coord will show where you got on the mount)

Bypassing the Attribute Points "cap"

Issue:
You can bypass the attribute point cap by switching characters and adding points.
Not sure if it's relevant to the "42949" points down at the bottom (another bug!), but you can only +1 point if you relog overall, you can't +1 to multiple lines.

Video Example:
https://youtu.be/gx-mAm2OF6I

Dungeons

• Instances
• 4 player and 10 player (and inbetween)
• Custom scripting to handle triggers
• Rewards
• Ranking system (S+, S, A, etc.)

Not enough space in packet: 66 00 03 01

Upon trying to visit the Maple Arena "Arena Shop" (And presumably some others, untested as of right now) the gameserver will crash with the following Exception:

Engineering

Implement unknown mode logging on handlers (ex: RequestItemInventoryHandler.cs)
Make each mode in handler handled in a different method (ex: RequestItemInventoryHandler.cs)
Use 1 packet file per SendOp
Replace all hard-coded modes in send packets with enums
Rewrite broadcast packet system
Implement full inventory handling
Remove all PacketWriter instances outside of standalone Packet files
Remove public void Send(params byte[] packet) inside Session.cs

Black Market/Auction House

- Buying items and deducting meso
- Listing new items
- Listing fees

• Searching/Filters (missing stats filter)
• Meso market

Crafting

• Taking required materials and giving result
• Giving experience
• Cost per item

Mobs

SOME WORK AS BEEN MADE BUT A COMPLETE REWORK WOULD BE BETTER

• Behavior
• Movement AI
• Spawning and Respawning

Cutscenes

• Cutscenes during quests / job intros

Minimap

• Correctly show player on minimap
• Show other players correctly (party, friend, etc.)

Fishing

• Mastery
• Fishing buffs
• Bait and special lures (events)
• Catching fish (minigame, RNG)

Taxis

• Figure out correct price formula for car taxis
• Save discovered taxis

Prestige

• Prestige bonus stats
• Daily bonus prestige limit
• Prestige milestone rewards
• Update on player profile
• Weekly missions

Mounts

• Air mounts
• Ground mounts
• Dual-rider mounts works fine, but three riders mount needs a little fix. Third player stays in the same slot as the second player.

Adventure (World Map Stars)

• Increasing adventure level
• Exploration missions
• Rewards

Guilds: Guild Focus + Emblem doesn't save, check-in shouldn't be able to work immediately, missing trophy

Issues:

• Guild Focus doesn't save the changes
• Supposed to receive a trophy after creating a guild
• Checking in shouldn't be able to work within the first day of joining/creating a guild, iirc it'll become available after the daily reset
• Applying for guild via the "G" interface crashes the server

NPCs

• Scripting
• Proper dialogue (currently can't converse with NPCs, they say one line)
• Quest dialogue
• NPC movement
• Npc's should look towards the player when talking

Clubs

• Editing buff

Leaving
Add support for kicking members
Editing name
Creating
Inviting

Remove infinity loops

• Remove Session from Player;
• Remove Player from Buddy and Guild;
• More??

Implement portraits

Issue:
Portraits/Icons/Logos/Avatars, whatever you want to call it, aren't saving. Most likely because it's to do with a UGC server so I guess this would fall under a feature more than a bug? Put it here anyway though :)

Video Example:
https://youtu.be/ADi2dEZOd-I

RequestItemUse deletes items it shouldn't

Right now RequestItemUse always removes the item used from the inventory, however, some items are multi-use. Currently the biggest thing is affects is Instruments which disappear after a single use. Not sure how to check for it, possibly in the item metadata.

Skill-tree (Archer + Berserker)

Issue Description:
The skills for Archer + Berserker seem to not allow points to be allocated for the first skill.

Skill effected:
Archer: Sharp Eyes + Eagle Claw
Berserker: Intimidation

Example:
Archer: https://i.imgur.com/P9sEVRK.png
Berserker: https://i.imgur.com/5oNRfaf.png

Traits

• Trait menu and increasing/resetting

Bug: Shops - Item stacks do not multiply with amount purchased

Shops

Reported by: sharr
Problem: I think item purchase does not multiply with ammount purchased, like this Onyx Crytals 24 limit, but 24 only is added to inv

Fix:

Item item = new(shopItem.ItemId)
{
    Amount = quantity * shopItem.Quantity
};

Spawning a Transparency Badge will crash the server

Issue:
Spawning in the Transparency Badge (ID: 70100001), will crash the server

2-handed weapons are rolled with 1-handed weapon values

Example:
A 2-handed weapon will at most have 5.6% Physical/Magic Pierce, or 1.6% piercing.
The correct values should be 11.2% Physical/Magic Pierce, or 3.2% piercing.

Just need to 2x the values for the 1-handed weapons on the 2-handed.

CharacterInfo

• Fishing mastery
• Music mastery
