Well. Its not much important. But the doors textures are messed up. In Multiplayer servers. The Acacia stairs aren't recognized and they turn into stone when put into your inventory. And the achievements are messed up. After a while of playing on a server, in the top right corner the "Press 'E' to open your inventory pops up, and you can't do it. It doesn't go away.
Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
