MC 1.17.1 Latest version of MCDoom
Texture doom:blocks/jump_boost with size 70x30 limits mip level from 4 to 1

It's all versions but eh would require a full remodel so it's one the "I'll get around to it but it's not game breaking" list

Closing this as it's now fixed but update won't be out until hopefully later today. Just waiting on a new model/texture to be sent.
