I had completed all the missions in Campaign 1 but had elected not to proceed to Campaign 2 yet. I had modded a bunch of stuff and was still testing it so hadn't copied the files to Campaign 2.
I was flying through the Lornak system and the game took an Invalid Floating Point Operation and crashed. I reloaded from the autosave, got to about the same point in the system and it happened again. I ran through all my mods and didn't find any probs. I played with this for a couple of hours trying different things until I finally thought to watch the Stardate. Sure enough, that was the trigger...when the Stardate gets to 2465.00 the game takes the Invalid Floating Point Op and crashes.
Not sure how far I am into it I am running P7N mod that way and get them from time to time, I do not think it has to do with the mods but maybe just a small bug, try going a different way into the system for a time and see

I started a new Campaign 1. I just let the game run and it took a Floating Point Op and crashed sometime after 2497(the Last time I looked at it). I hadn't modded anything for Campaign 3 so I started a game of that and just let it run. It took a Floating Point Op in 2494 and crashed.
Uninstalled and reinstalled the game. Started a Campaign 1 and just let it run. It took a Floating Point Op in 2484 and crashed.
Looks like this is something I'm just going to have to live with...
