Android Saving Differently Than Engine Tests

Hey, guys.

I've created and tested an inventory system in my in-engine version of my game. It's a drag-and-drop interface, and it's supposed to save what items you have and what slot that item is in (wether it is in the backpack or equipped). I've tested it on my computer and it works just fine. However, when I built it to an Android it will sometimes move all the items in the inventory to the head slot, instead of the slot it was in. I have not yet been able to find a pattern for when this happens, so I don't know what can be causing it. I've tested side-by-side with the engine version of my game, doing the same exact thing on both, and the engine saves it correctly, whereas the Android puts everything back in the head slot. So, my question is, what could be causing this? Do you need more information on how the inventory works? Do I need to do something differently with the Android?

Thanks!
