Brick and Mossy Stone Brick Walls are bugged

[Beatso]

The textures do not correspond to what the blocks (& slabs and stairs) use for that same block ; i.e. A brick block placed in the same spot as a wall will have a different pattern of bricks (say dark-light-normal) for the top row as a wall (which would have say dark-normal-normal), however, slabs, stairs, and full blocks share the same texture, not sure is that is a bug but still useful to point out ig.

The blockstates and models for the walls are very different to the block/slab/stairs, so I don't think this is part of the issue.

Ok so basically the bug is because when the block has the blockstate west=tall, it is meant to apply one of four variants of the tall side model, bug in the blockstate file it is only applying one:

"when": {
  "west": "tall"
},
"apply": {
  "model": "minecraft:block/bricks/wall/side_tall/1",
  "y": 270,
  "uvlock": true
}

This means on all but one variant, it is using the wrong texture, causing this issue.

Fix

The blockstate file should choose between all four variants of the side_tall model.

This is also an issue on mossy_stone_brick_wall.
