When moving things around in the inventory, while equipping your characters in the armory for example. I get this glitch all the time where the item I try to move to a certain slot just keeps jumping back to the armory screen and vice versa. It happens constantly and I have to give it like 5 tries each time to get the item where I want it to be. As you can imagine, this is highly annoying. ;)

Anyone else have this problem and/or know a fix for it?

What you need to do is to just click the item, then click it at the square you want it to be, it's rather fickle how the inventory system works.

Yeah, I have noticed you have to put the item *exactly* in the middle of the square to make it work. Quite an annoyance. :P But what's worse, it seems sometimes when you don't do it exactly right, the item completely disappears. :\

ACTUALLY. When that happens, the selected character dropped it.
A pain when your in the base and they're behind a desk. and you don't have to click inside the square exactly, just click it and click the area on the grid, dragging is what causes the problems.
