I see, the vickers gunner got sniped by an incendiary round just in the milli second where he finished the de-setup process. This bug looks extremely rare to me and actually this is the first time I see it.
Were you not able to set it up anymore, even after the crew got killed and re-crewed?
I wonder if it's possible (technically) to add the Jagdpanther to the game, with same look and sound files like in vCoH and copy paste of the King Tiger voicelines
