As i can’t play my main singleplayer game anymore (at least not much longer than 5 minutes) i spent 3h on #3181 building a tiny 2x2 emergency base and then running around sightseeing (sepermeru to pirate bay). What can i say: besides the horrible teleporting enemys which made fighting a pack of hyenas with a stone sword and wooden shield quite challenging (i choose to run) it works flawless.
On my PS5 (game on internal ssd) i have one working singleplayer game, one which is unplayable and i can play on two official servers without problem. I think this rules out a faulty installation as well as as a faulty game database as you can’t play on the same server/same database i can.
