Regions Unexplored is a biome mod with tons of wood types and it feels off when using it with quark cause ill have something like that has really cool chest designs and then theres all the ones from regions unexplored that are just a variant of the oak one (that colored variants are every compat)

@Vazkii This is broken in version 1.20.1. When trying to craft a chest with ANY wood type from Regions Unexplored, it doesn't work at all because of Quark variant chests. Quark is trying to find a variant chest for Regions Unexplored wood types but it doesn't exist. But unlike before, it doesn't default to the vanilla chest.
