Duplication bug - works on any item

[K-Fitzpatrick]

Describe the Bug

Using Sophisticated Storage's Stack Upgrade and Supplementaries' Sack, you can duplicate any item you have more than a stack of (including unstackables).

Reproduction Steps

1. Put more than 1 full stack in a Sophisticated Backpack with a Stack Upgrade
2. Left click a Sack (to hold it)
3. Right click the overfull stack
4. The Sack will contain the full amount of the Backpack stack, but the Backpack will have only lost 1 stack

report it to the Supplementaries developers please

They say it shouldn't be an issue in later versions, does SteamPunk need to update the one it uses?

[chorbintime]

yes, it'll be updated in the next modpack update
