Both of these crashes seem to be an interaction with another mod.

First crash is with dev.latvian.kubejs.player.InventoryListener
java.lang.ClassCastException: dev.latvian.kubejs.player.InventoryListener cannot be cast to net.minecraft.entity.player.ServerPlayerEntity

Send crash is with com.feed_the_beast.ftbquests.util.FTBQuestsInventoryListener
java.lang.ClassCastException: com.feed_the_beast.ftbquests.util.FTBQuestsInventoryListener cannot be cast to net.minecraft.entity.player.ServerPlayerEntity

Both of these are triggered off the Woot InfuserContainer class.

As of yet I don't know if I'm doing something wrong (possible) or the other mod is wrong (also possible).

Looks like these mods add a new listener to listeners list. I just walk over them and cast them to (ServerPlayerEntity) which clearly, as the crash shows, they are not. So I'll need to check for the correct type and ignore those ones.

So this is a deficiency in Woot. I'll get it patched up.

Fixed in 1.15.2-1.1.0.3
