Crash and Error when trying to load a save

Maybe you have mismatched versions? What kind of install do you have? (Origin/Steam/disc) Normally, the best thing to do would be to go to NRaas, list your mods, and ask for advice. But the site is in transition right now, of course, so maybe you could just list them here, along with their versions. (If you have outdated or mismatched mods, that could be causing your issues.) If you have any scripterrors left over, the NRaas mod versions should be listed at the bottom of the page.
