I'm seeing the cycling 222, 224, 2339, 2608 errors (all Object reference not set to an instance of the object) on transiting an unexplored jump point (this looks to be linked to NPR generation, and goes back to at least 1.7.3). 1.9.4 installation, TN start on 1.9.3 or 1.9.4 (can't remember offhand), nothing particularly exotic going on. I did move the save from one computer to another, but I've had no other issues, and I deleted the database instead of pasting over.
Real stars, less than a year into the campaign.
Oh, and one other thing. After I got through the errors (took quite a while), I noticed that the oxygen percentage on the probable planet was 31.69%, which puts it into the "dangerous atmosphere" region, IIRC. Not sure if that's related or not.
