Putting any cooler into the icebox using shiftclick on the server creates ghostitem or sometimes duplicates the stack.

Version of the mod: ColdSweat-2.3.7 (i noticed it on 2.3.6 too)

Forge version (both server and client): forge-1.16.5-36.2.42

What do you mean by "cooler"? Because in my testing, neither fuel nor waterskins duplicate when shift-clicking them into the icebox. Shift-clicking normal items around the inventory doesn't do anything abnormal either

I mean fuel (snow, ice etc.). I tested it on a stable localhost server with no lag and only this mod installed. Everytime it creates a ghostitem like in a video.

Normally it's not a problem, because the ghostitem ussually disapears but I'm planning on using it on heavy modded server where those ghostitems sometimes turn into regular items.

There must be some kind of external factor affecting this somehow, because I still can't replicate this issue. Using Forge 36.2.42 and only Cold Sweat 2.3.7, items shift-click just fine.

I have no idea what might be causing such a bug externaly, but i guess I'll try to find out. Thanks for help tho.
