After sniping and boarding Large Oil rig I looted a few bodies and by the time I got to the red door and swiped the keycard the locked crate despawned. This was happening last month as well..upon looting scientist, boxes and anything first the crate would often despawn...So even after it happened we tried it again this time tried to hurry (not sure if despawn is time related) and were careful not to loot anything and the crate despawned again after swiping the red keycard. I tried looking up to see if i could find a similar issue but couldnt locate anything but was told it was a known issue and I wasnt sure if it was supposed to be fixed or not. This also happened to small rig last month and I was informed it is still happened there again also.
