I think we should have the ability to redownload/reinstall just the texture files when we need to, because for like a week i've had a problem where the bottom side of most blocks has had the texture cut in two diagonally, so next to another block of the same type the texture looks like a rhombus and it's really annoying, and the trick someone told me fixes it for them (press f1 or f3, they weren't sure which) didn't work for me, and since it's consistent i image it's probably an issue with my textures installation. It is on a server.
