Deimos vault necramech bugged

[QneCTd]

At August 1st i was playing with 2 friends and one random player, while the bug occurred.
While we were doing vault mission, my friend had deployed his necramech, i was aiming at it and jumped in his necramech instead of operator form.
Not only i was able to control his necramech and dealt no damage, but while i died to try swap to the frame again, my game was frozen, everyone was standing still, yet i still had internet connection with host. The point is, i was able to jump into another player's necramech, but more importantly i didn't get loot after they completed the mission.
I attach screenshots of what should i got, but didnt due to that pesky bug.
Sincerely,
