Did anyone found a fix for this ? I've reinstalled FNIS/XPMSE and had XPMSE.esp at the bottom of the load order but the game still manages to find something to bother me and pop the error.
Honestly this bug is hard to reproduce. After getting this bug initially i did a complete reinstall and i haven't had it since. The best way i found to fix this is to do a complete reinstall of skyrim and all mods. delete everything.
Wow, that's such a brilliant solution - that would solve the problem in only three days! Provided of course, that it doesn't reappear after the re-installation - which it would, if the same mods were installed....OMG
BUT at least I found a workable solution: I did as recommended earlier in the thread and installed the "Continue game - No crash" bug fix:
And NOT ONLY did it solve the crash problem IMMEDIATELY (the game had started crashing with this error 50% of the time, but the crash frequency increased, so that my last 20 attempts to load the clean start save I'm using, resulted in a crash), it ALSO solved the error message I got from Sexlab (Sexlab framework). While before it would report that Sexlab wasn't properly installed, it now reports all modules, including the "FNIS for users behaviour" and the "Sexlab idles" that it earlier reported as uninstalled - as installed. So it seems the bugfix assured that the loading sequence finishes without a crash. Many thanks to the author
