I just loaded the maxihub mod and installed it to my server, but I noticed that many items like "Yeti wool", "gunpowder, ..." didn't appear in the item drop rate. Like a "gunpowder" that drops on a loot crate "yeti wool" will kill the yeti that will fall.

Someone helping me to add these items to the item drop rate, thanks

For animals u can use something like this: https://umod.org/plugins/animals-loot-manager
