Same problem since a few weeks. At first it was every 15 Minutes for about 2 minutes, after those 2 minutes everything was okay again for another 15 minutes.
But at the moment it starts right after connecting. I can do like maybe one action (Eat, drink) and after this the game is desynced.
No matter which server or time.

Got the same issue, but it seems just to be a graphicbug. Stand under the loot and you should be able to pic it up in the "environment"-section in your inventory. Cause the loot seems to be placed on the ground, but the graphic just got up to the roof.
