Quad Stash Tab Weirdness

Items do not want to be placed where they should fit perfectly fine. Issue seems to happen when the empty inventory squares are surrounded by other items. Seems like some tetris code gone bad! :P If I close the stash, re-open, sometimes it will work where it didnt want to place an item before.

Tried a million ways to grab and move them to the spot I want to place and they just wont go where I want. If the surrounding squares are full of other things next to impossible to place.

In this use-case it was a Quad Guild Stash Tab.

EDIT: This situation gets worse.

If you have an item under the mouse active and try to place it somewhere another item sat. That item underneat the mouse gets bugged out and cannot do anything with that item anymore for X period of time, as if some code is timing out. You would think the logic would be OK lets PLACE the item and pick up the UNDERNEATH item... but no the UNDERNEATH item gets bugged out, cannot move it, withdraw it, nothing.
