What the hell?

Relaunch your game. You probably changed a video setting or switched a resource pack and it screwed up the texture atlas.

Ok, the issue here is that changing the mipmap setting ingame is changing UVs, and our model cache is not being refreshed. This issue should actually fix itself if you don't update the blocks for a minute ;)

Easy fix, will do it tonight.

If that's the case, it's a bug on our part. However, we don't cache any UVs outside models so I doubt that....unless something modified the atlas without causing a resource refresh.
