Ars Magica 2 Arcane Reconstructor Dupe Bug

[BluGen]

If you have opened the GUI of the Arcane Reconstructor and put two or more of the same stackable item in the lower slots of the right inventory. Then shift click the items und you get more items back than you put in. If an item of the same kind is in your inventory, the bug does not occur. Also the upper slots behave properly.
I hope I could describe the bug reproducable.
Also I am using Direwolf 20 1.6.4 Pack @ 1.0.16
