I mean, its a fun game but like. IT IS UNPLAYABLE. I save or sleep and it crashes. I start up a brand new world, 3-4 hours in, i sleep and it crashes and now I have 2 save files that I just cant play on.
From what I see, its only happening in solo player worlds.
Can you please fix this ♥♥♥♥ man like this is so ♥♥♥♥♥♥♥ lame.
Its a very fun game but i dont wanna wait an entire week just to be able to play the game properly. Like why does it work perfectly up until A certain point. I can save the no problem then all of a sudden, stops working.
