Duplication glitch

[BirdieMiner]

Hey! First of all, love the mod, it's been really fun to play with!

I just updated the mod, and I'm having a weird issue with the Forge 1.20.1-1.0.6 update (playing on 1.20.4), where if you pick up an item that's been added as an exception, it will sometimes duplicate a huge number of that item, like completely filling the inventory (and when I use the Physics Mod, it also drops a framerate-killing number of stacks of that item, along with any other item in the inventory that's also been added as an exception, I have no idea why lol). I couldn't get it to work in the 1.0.5 version, so I assume it's being caused by a recent change

The issue happens even when it's the only mod I have in a newly-made modpack, so it's not a compatibility thing, though it may just be an issue with my system in general? If I drop like 10 of an item then stand on them to immediately pick them up, it's guaranteed to happen

Can you send your modpack to me and tell me how to reproduce?
