Describe the bug
whenever my backpack is full it's like everything stacks on each other for just a second resulting in one item being left in the top left slot

To Reproduce
Steps to reproduce the behavior:

1. Open backpack
2. fill slots with many items (possibly from different mobs)
3. input/click sort
4. See error

Expected behavior
backpack inventory sorts accordingly

know of any other mods bigger stacks doesnt work well with?

I can't do anything with that list, if you can get me the minimal one with which that issue happens I can take a look

the issue is with bigger stacks

Right yeah, they do intrusive incompatible changes to sophisticated as far as I recall and I am pretty sure it's not just when you are sorting but in other situations as well. You have to decide whether you want to use sophisticated or bigger stacks and just use one of them.

I have no idea, but I would guess any gui mod that allows transfering stacks between inventories, mods that allow having larger stack sizes those would be prime examples of mods that could have issues.

Are you able to recreate with only SB in the pack?

sometimes it works, sometimes a handful of items stay, sometimes everything deletes

i'm not able to replicate it

it seems to work just fine isolated

should i post a list of the mods i'm currently using it with?

I will need steps how I can recreate and instead of list of all the mods I would need a minimal list of mods with which it you are able to recreate.

here's the modlist i'm using
