This exception

java.lang.NullPointerException: Cannot invoke "net.minecraft.core.HolderLookup$Provider.lookupOrThrow(net.minecraft.resources.ResourceKey)" because "registries" is null

happens a lot with other mods actually. For this issue, my guess is that the setting of the registries from the server doesn't happen until later. But I'm also getting this issue when loading chunks (usually when piglins spawn), which my guess there is that it tries to get the registries on the worldgen thread, which isn't the same thread as the server, so there's no registries for that thread to get?
