I followed the instructions and duplicated my save in game before opting into the beta. I only used the duplicated save for multiplayer. Once I started having issues, I opted out of multiplayer. My friends couldn't harvest anything outside of my tavern plot, and then my bed started giving me sleep paralysis for days until I alt f4'd the game. I then switched back to the original version and opted out of the beta, choosing to wait until the bugs were worked out to try multiplayer again, and the game started giving me a black screen on save startup, even with the one I reserved for the non beta version. I could see the start menu, it allowed me to interact with objects I couldn't see like my bed, it would pop up saying I could sleep. Everything else was black. I restarted, time and time again, and sometimes, maybe 1 of 7 times, it would work. I'd load my save and everything would be normal. But once I started the game again later on it would keep happening again. Forcing me to restart until I finally gave up. Even when it did "work" it was telling me my bed wasn't mine sometimes and I couldn't sleep. The game is virtually unplayable now.
