Minecraft Version: 1.16.5
Mod Version: lootbagmod-1.16.5-1.6.5.jar & lootbagmod-1.16.5-1.6.6.jar

Describe the bug
After the recent updates Loot bags no longer drop when killing endermen or creepers.

To Reproduce
After updating not a single loot bag dropped after killing over a 100 creepers and endermen. Even using a sword with looting 50 resulted in no loot bags dropping.

The configs were not changed. Only the mod was updated.

Rolling back to version lootbagmod-1.16.3-1.6.4.jar results in bags dropping again.

Expected behavior
bags dropping when mobs are killed

The mob drop config was changed to use registry names

so for creeper you need to use minecraft:creeper instead of just creeper
and for enderman you need to use minecraft:enderman

I'll try again to delete the config and then update.

That did indeed fix it. Though can I strongly recommend mentioning this on the main page of the curseforge page.
