My 700 day save can no longer be accessed. I have traveled in RoG to the next world with Teleportato and constructed about half of my new mega base. I traveled to the Hamlet world at day ~80. To my surprise the Hamlet world was not reset. The game was lagging hard, but after ending Aporkalypse I decided to go to the Shipwrecked world to check if that world wasn't resetted either... And here is where the game refused to load it, giving me Out of Memory error.
I have turned off all my mods, enabled all performance options, and it still just can't handle my old SW world.
I would like to point out that I had the same problem before, but just enabling performance options fixed the it, and I don't remember adding anything to my SW base that would overload the game.
I have made a bug report in-game.
Have big bases in every world and attempt to travel between all of them.
