Tried to cross the small stream that runs East to West on the Southern border of Severograd. A large rock was on my right hand side as I attempted to cross. Got stuck and was not able to turn to look or rotate my body once I was in the "hole". I could only look up and down along the y axis. Was a few feet into the stream crossing from South to North about midway through the town. Was falling from about a foot up and starting about a foot higher my standing character would lower himself a couple of inches at a time, until the process would restart, beginning at the top. Drinking from the stream did not pause or stop this falling phenomenon. Vaulting, different stances, and shooting my gun did not help. Before all this happened, I did manage to get out by sprinting maybe a couple of seconds after falling the first time. I went back to reproduce it. I had to suicide to get out.
