I have been grinding for rank V France ground I have got every researchable tank except the light tank line and I have the battle pass M46 but it is saying that rank V is locked even though i have enough rank IV tanks for it because the message “you must own x/6 vehicles of the previous rank” has gone away and it now just says “rank V locked” I need help ASAP because I would not like to waste time worrying.
