I was using my IS1premium against Germany in Berlin, Bombs dropped nearby and I was damaged and tracked both sides.
I waited til it was clear then made commander jump out, it showed prompt to repair holding square, the wrench appeared but when I highlighted the tracks I was unable to repair them???
My recent experience was with IS1, but I am just curious anyone else had same issue? Perhaps a different tank or vehicle?
I have a short video I will upload later when I get back home.
