dankstorage-1.19.2-5.1.2
dank 2 with all slots used will replace all items in all the slots with a stack of a single item if used with mouse tweaks middle click sort option (e.g. if you middle click on a slot containing cobblestone, all items in all slots will be replaced by 1 stack of cobble)

Mousetweaks bug, nothing I can do on my end.

Can confirm. I was so mad when I accidentaly sorted and it deleted EVERYTHING :CC

Mouse Tweaks does not have sorting functionality. It's some other mod.

I confirm. SimpleInventorySorter deleted a lot of my items accidently. Its extremely frustrating. Is this possible for you to forbid other inventory sorting mods from touching Dank inventory?

I've banned quark in the past for incorrectly implemented item sorting, I don't have the time to prevent every mod from touching the slots.
