I had just completed the Master Crota’s End challenge for the week and received loot. I returned to orbit and then went to the tower. I went to deposit the loot and I also tried to deposit a crafted Syncopation-53 that was in my inventory. When I tried to deposit that weapon, I was kicked from the game with error code WEASEL. When I logged back in, all my loot from the recent raid challenge completion was gone. The loot was neither in my vault nor in collections. I lost an adept Oversoul Edict because of it. Not realizing what the cause was, I tried depositing the same weapon again and was kicked again. I was able to reproduce this at least 5 times in a row consistently and when I made the tweet about it, other users confirmed I am not alone in this. Please acknowledge this as it is a very serious issue.
