I ended up just finishing that save and starting a new proper multiplayer with my brother. So that world is gone, no harm done now. Just weird issues.

I was able to find the issue. Headed back to Nauvis and found some bitters homed in the start area. I cant kill them otherwise it crashes the game again. Was able to get the game to launch by downgrading back to 2.0.15.

My old save game from last week, I had some pc issues and haven't been able to play. With the update I am unable to load this game in either single or multiplayer. Getting a consistency check when it goes to load. I REALLY don't want to have to restart as I'm right at the end of my first Space Age ...
