Game mode: [Singleplayer]
Today, crashes are happening every few minutes on singleplayer co-op. Host connection is fine, but those playing with are booted to black screen frequently. Sometimes minutes after joining, sometimes after an hr or so. We actually play co-op locally, multiple consoles in one house on the same internet. Usually issues are rare. Internet connection is fine, speeds actually better today than normal.
Note some other weirdness today - diving in water and chopping with pickaxe both felt “off” from the normal feel, and every menu open took 5-6 seconds.
