I spent several hours testing and trying to figure out which god forsaken mod or mods was causing this issue and all I had to do was google "skyrim loading save hangs" and click on the FIRST result to find this thread and the answer. Which, of course, took SECONDS... not the 3 or 4 or 38470920432 hours I spent on my own. ARGH! The only reason I spent so much time was because when I unloaded ALL the mods, the problematic save was able to load up without any issues. When I systematically tested various mods and combos of mods, sometimes the save would load. All the damn signs pointed to a a mod issue! SIGH... Ah, sorry... What I meant to say, to Adwath, is THANK YOU. I was aware of map changes in the skyrim.ini causing CTDs but not this type of hang up thus I never thought to test for it. <--- dumbass Again, THANKS!
