Sorry, i meant Pavlovo base, my bad. In pavlovo the player gets stuck on multiple segments and maybe even all of them, i tried getting OUT of the military that way, haven't tested getting IN. And it also happened in Arsenovo, but not sure which direction it was. My guess is that it happens where the ground is a bit too steep. When i got stuck, i tried going both back and forward, and even rolling, but i couldn't get out. Hope this helps at all.
