In the image my tank has two crew left. Both of them are drivers and the gunner and loader are dead. Neither of the drivers go to take the position of the gunner leaving me as essentially the most useless tank in the entire game. Could it be because of the 1% packet loss causing de sync with the server? Possibly, but this is something I have only experienced in dual driver vehicles.
Had that bug on my pack ouma they still didn’t really fix it
You can bug report it here (just search a bit first so that you don’t report something that is already reported and known about): (Gaijin.net // Issues)
A guide on how to report bugs can be found here: ([Navigation] Technical Knowledge Base | War Thunder Wiki)
It is such a bogus bug that only happens on some occasion. A lesser version of this bug is the crew taking 5 seconds to go oh shit Nigel died and then they prompt the gunner replacement.
