For 1.16.1 Quark Oddities, the totem of holding appears as the missing texture block, the cube with the purple and black. I am not sure how to fix it.

Do you have optifine? IDK, just sounds like the kind of thing OF would do, but it could be an oddities problem.

Yeah I do, well, that is a shame since I can't play without OF as my computer would have less than 10 fps. Do you possibly know any way to resolve this issue? Thanks!

Unfortunately, there really isn't much you can do. I guess just not die lol
