I also have this issue, but a friend reported it for me
(because i can hardly be bothered to log into the forum).
Now try to imagine how many people:
a) run into this issue
b) even realise they have been demoted (instead of thinking “oh, must have forgotten/misremembered what rank i was”)
c) bother to create an account for the Fatshark forums (looking at the console players expecially)
d) Bother to make a report here
[e) If they see that it’s already a known bug, they might not bother reporting it again]
So i guess there is quite a large number of people just staying silent for one reason or another.
