Almost every other time the game autosaves, I am disconnected from the host, who is on Nintendo Switch. This only recently started happening today, but it rarely happened a couple times previously. I am playing on PC. It used to only make the game almost unbearably laggy, but now this started happening and it's making the game genuinely unplayable because it sometimes disconnects me EVERY time the game autosaves.

The world size is around 30 megabytes, and the attached image is what I get when I am disconnected.
