The little lake south of the Polana factory structure (east of Polana) is still buggy. When you enter it for getting water for example and get to close to the stones near the factory wall, you will propably clip into the ground again and again. When you do, you cannot turn your char (only the head i guess). Only movement possible is changing stance and the epic sidekick <V>. In result you cannot exit this zone. Moreover you cannot respawn, so you are damned to wait until somebody kills you. No chance to play DayZ SA until this happens.
