I was in a T34/85 last night and it tipped, however it didn't stop rolling from side to side(tip to the left hit the turret top and then go to the right. This lasted for about 2 mins, all the time I was trying to move fwd and ended in first gear and righted and continued as normal.
Also in the same GV I move sideways before moving fwd.
Sorry I didn't save the film but I'm sure I can get At least the sideways start up on film later today.
