I was playing with my friends, when one of them received a hit and asked to help him getting up, there was a bug in the server and he was disconnected from the party. When he got back, his armors were lost (they were not inside his bag nor with him). They have just vanished from our world. What could we do to solve this problem? Our armors were in level 6 and 7. This was not the first time we face this bug. We have lost a lady bug full set the first time and a  full set of pill bug.

Yeh same thing happend 2 us like 4 times and the pich wacker 

Happend to me today as the host

I was searching the black ant hill and kept dying. Upon retrieving my backpack my previously equipt items where not there. No other backpack icon. I searched the floor of the all the black ant tunnels and no weapon icons to be found or dropped gear. I lost my pinch Wacker level 6 and my level 6 ladybug armor. Very frustrating considering I've dumped a lot of time into the game.

The same thing happened to me too. I have lost my equipped armor and a tier 2 mace. Perhaps the problem is related to the fact that while returning to retrieve the backpack, I collected some items during the trip. So maybe when the backpack was collected, there was a sort of conflict with the maximum number of transportable objects and some of these were automatically eliminated.

We've had this same issue on the PC Gamepass version today; someone DCing while downed.
