Been playing since launch and have gotten quite a lot of crashes since then, recently I had noticed that it happens to mostly when my character is inside the lair or loading into a populated area. However today I warped to my base and now it immediately crashes upon loading in and I haven't been able to log in since on that character. Hopefully this gets fixed as soon as possible as my character is unplayable right now. Will update.
This really has been becoming a huge issue on the Switch... I crashed three times yesterday alone, and it's random with seemingly no rhyme or reason to it. On the player-run Discord server for the Switch, many many people have been also claiming to have these crashes. It's a server-wide issue and no one can seem to pin-point a cause. At least for Switch players.
