This thing happened to me today also. I played a Woods raid and managed to get to the extract. I had some time left (maybe under 10min.) and I tried to extract. After the extract I got the survived status, it showed me my scav and player kills, showed me my exp and all. Only thing that was missing was my ending loadout. After I skipped that screen, the game said to me that I had left the raid via disconnect. It gave me an option to join back in and ofcourse I tried it. After I tried to connect back to the raid, the loading screen said to me that server connection was lost, and I was back in the menu screen. I checked my inventory but all of my loot from that raid was gone. Like the raid never happened. I'm not mad or anything, I just hope someone who is involved with the development sees this thread and could tell us what happened. Thanks.
