After diverting power at the power plant, the save action causes the game to crash for me on Nintendo Switch.
Luckily, I have a save file where I can save without crashing. But once I move a bit away from the entrance to the power plant, saving makes the game crash.
I'm happy to provide the save files, though I'm not yet sure how to get them off the switch. The issue is very easy to reproduce with the save files, but I'm not sure why they are getting corrupted.
Some people on reddit have a similar issue: https://www.reddit.com/r/theouterworlds/comments/jlkafz/the_outer_worlds_keeps_crashing_on_the_switch/
