Honestly don’t know what causes it, trying chatting a lot or doing things that require a lot of animation but nothing triggers it so easily. I’d be casually walking around and the screen would go black or freeze, everything would work though. Buttons can be pressed and is annoying if your in a tight situation and it freezes or blacks out as you can still move and attack, but you cant see anything your doing. Haven’t gone out of my base for longer than 15 minutes, really annoying. Hopefully you can fix this soon!
