Singleplayer or multiplayer: Singleplayer
Steps to reproduce: Paxel is unable to mine marble (breaks it) even though it says it is a diamond level pick. When used on sandstone, has no problem mining full blocks and slabs but has issues with stairs and walls.
Additional information: First noticed after installing and uninstalling resource pack: Soartex Fanver - Modded.

BC doesn't add any paxel or marble, please report this to the mod that adds said paxel
