Complete Loot disappeared/// UI Overlay Error

I I‘ve captured two minutes of my Gameplay, because you must see what a big problem I had. I‘ve done a map Event and my Screen was full of very good Loot, I wanted to pick it up after the event in map is over, but then It was not possible to Pickup Loot, the whole Textboxes for every Item drifts with my moving character and direction of him. You can see in this video, that this drifting Loot disappeared completely. I am so sad damn…

Guys can I upload this video here?

You must see

Edit: I teleported to town and back, then it was working to see and pickup loot ^^
