This was the 4th time when I (host - engineer, no bomb at hand) purchased the morgrim, gave to the other who had duplicate then it was only just a simple bomb. There was time when I had a bomb (engineer), there was another when I had a bomb and did not changed to the morgrim (WHC), leaving me with the normal one, and the 3rd when I had no bombs, still got a simple one.
It didn’t changed the existing one to morgrim, or I did not give it at all. Just a simple bomb.
