I am playing a multiplayer online game with one other person (both on XBox, my partner is on Series X and I'm on One) and every time I go in or out of a big base (not that big, just a 3x4 house, a smaller curved building and the general bits & bobs like cooking spit etc) it lags majorly (this is the best case scenario), completely freezes for a while, or straight up crashes and kicks me out of the game. It's become unplayable now  Please fix this ASAP! Or give me some suggestions of how to get around it?

It's now got to the point where it freezes as soon as it loads in, and never unfreezes. If left long enough it will kick me out of the game. The game is now completely unplayable for me

I can't even get as far as making a wall before it crashes

Hey Emily! I apologize for the frustration that you've been experiencing while dealing with these crashes. Can you please submit a support ticket so we can work one on with you to try and resolve this issue? It sounds like this is related to a connection issue. The team is aware of players dealing with this and they are continually working on network fidelity throughout the Game Preview/Early Access phase of development. 

Thanks
