I made a ticket about the fishing bobber, fox, and turtle textures offset/pixels shaped incorrectly. These haven't been fixed but I also have noticed that I am unable to post sheep textures with it saying "Invalid aspect ratio for model". The aspect ratio is the same as vanilla's texture and there is no reason that it shouldn't be working. I have tried to do it on other search engines to see if it was on my side but I'm quite sure that it isn't.
