[Bug]: Duplicate Capability Key

[TheIllusiveC4]

Does this happen with only Curios loaded?

I also noticed that you have Sinytra Connector installed, does this happen if you remove it?

I am getting this same issue when trying to run the latest version of Beans Backpacks.

I get the same issue but mine just full on crashes the server, this is the beginning of a very long crash log, for me it crashes with elytra slot enabled, if its disabled it works fine:

[ne.mi.ev.EventBus/EVENTBUS]: Exception caught during firing event: Duplicate Capability Key: curios:item com.illusivesoulworks.elytraslot.ElytraSlotForgeMod$1@30e36fc9

Are either of you running Sinytra Connector as well?

I am not

Usually this is a result of multiple mods trying to add the same capability to an item. My suggestion is to try and remove mods in order to isolate which ones are conflicting with each other. In addition, it may be beneficial to begin with a bare minimum environment with just Curios API and a couple other mods to verify if it's a Curios bug.
