Hello,

I'm playing SkyFactory 3.0.5 (Draconic-Evolution-1.10.2-2.0.7.168-universal.jar), I was setting up my T7 energy storage when I shift-clicked an item stack (redstone blocks) while having the energy core GUI open.
I just wanted the stack to go into my hand to place them after closing the GUI.

Here's the log :

Quite long because of an "infinite" loop before call stack gave up.

Will be fixed in the next release.
