How to Clear or Reset a Mob's Extra Drops
Clear a single mob
If you added drops to a mob and want to start over, use /cemd cleardrops <entity-name>. Replace <entity-name> with the mob's entity ID. This removes all extra drops you configured for that specific mob, leaving other mobs untouched. It is the fastest way to undo a mistake without hand-editing the config.
When to use it
Use this command when you added the wrong item, when you want to redo a mob's drop table from scratch, or when testing and you need a clean slate. Because the mod stores drops per mob, clearing one mob does not affect any other mob's entries.
Confirm the change
After running the command, run /cemd reload if you also edited the config manually, or simply check the config file to confirm the entries for that mob are gone. Kill the mob to verify it no longer drops the extra items. If you want to remove only one item rather than all of them, edit the configuration file directly and delete just that entry, then reload. Clearing drops is permanent for that mob, so note down any items you want to re-add before running the command.
