I lost all my items in a raid because of a bug.

We were doing a quest in a swamp with locked zones, and I was simply knocked underground, unable to escape, and died, losing everything. You can see everything in the video, including my belongings. I died at approximately 5:08 UTC +3.

Also my previous death, where I had two golden weapons, was also due to a bug. We were playing at an outpost and had over a minute to exit the main area, but we couldn't get through the tunnel because there was an invisible barrier blocking our passage. The entire team ended up dying because of the bug.
Please look into these cases and return the items if possible. Thank you for your help!
