I'm still reading that people have to reload the game once they get a black screen while trying to join their friends. I've recommended this game to my friend and he purchased it and we have yet to experience any bugs in the eleven days we've played. But we haven't set up a base camp or accumulated a lot of items. We'll be setting up a trash can and a composter in the hope of preventing lagging and potential unwanted despawns. Also the XML file is getting large because random guests are joining our public server and their data never gets deleted as far as I know. As updates keep coming, I will be recommending that more friends buy the game!
