On the most recent 1.12.2 version of the backport some textures are broken and the cross bow doesn't even work.

Heres a list
Campfire - Broken texture plus doesn't work.
Cross Bow - Broken texture plus doesn't work.
Sweet Berry Bush - Broken texture.
Bamboo - Can't be farmed due to it not being able to be placed. Its name is item so idk if this is intentional or not because it makes no sense you can't farm something meant to be farmed.
