It’s happened to every official server I’ve joined in the last 2 weeks. I’ve joined a total of 5 (I don’t remember all their numbers) none of my friends play on the official servers since we have the private server but i wanted to try out the base game a bit, maybe meet some new folks cause the private server has been kinda dead.
I get no notice but it happens with every official server I’ve joined after several hours of gameplay. I get to about the same point each time: build a base, unlock iron weapons, and apply my first base expansion for a wheel of pain to start collecting thralls and around this time, I either get disconnected or I logged off myself. Either way, the official server vanishes
