Minecraft version: 1.12
Environment: Singleplayer

Mod name: humbling bundle

Description

humbling bundle duplicates items that get picked up by mobs
which makes it possible to dupe item containers

It's still happening as of 1.16.5 for armour and weapons. This is hilariously ridiculous in mob farms, where the mob picks up the gear, doubles it, gets killed, then another one picks up the gear, doubles it, gets killed, and so on so forth until it's a huge uncountable power of two. I haven't encountered any crashes, but this seems kind of unstable.

Well found! I've fixed it in version 1.2. Thanks for letting me know.

I see that you're using 1.12. I don't normally update it but I've made an exception. A 1.12 version is available on the files page too now.

thank you so much its working great!

This is still an issue on version 1.3 for Minecraft 1.16.5.

Skeleton bows are also duped. I recommend preventing any unstackable items from being duplicated.
