Information

Minecraft version: 1.21.1
Modloader: NeoForge
NeoForge version: 21.1.83
Environment: Singleplayer

Mod name: Configurable Extra Mob Drops
Mod version: 1.21.1-3.4

Description

Doing "/cemd addhand cow 0.5" with a potato in hand adds the following line to the mobdropconfig.txt file:
'minecraft:cow' : '{count:1,id:"minecraft:potato"}',
It doesn't add the dropchance tag to the drop item as it seems like it should, and on the death of the cow drops one potato on each death.

Having this same issue, Is there a way for me to write it in by hand? latest version of 1.21.4 on fabric.

I can confirm this bug remains on 1.21.1 Neo forge. Fresh Java server, drop chance does not work.

Neo forge 21.1.93

Thank you for opening the issue and giving the mod a try! This has been fixed in version 3.6 of Configurable Extra Mob Drops. Apologies for the inconvenience.
