Pixative

I have stack sizes mod and also xskills, with cages set to stack like most things. I crafted 2 cages and had them in my hotbar, and went to catch chickens. I expected bucket-like behavior where the filled cage would move to another slot. Instead, both cages became filled with the same chicken, duplicating it. Not world-ending and not a problem with the mod per se, just a collision I wanted to report.
