My Game is having the same problem when I begin at Skuldafn as well. 117 Active mods 140 Active Plugins total. Main character has (wild guess here), over 100 hrs play time. Peace talks save runs ok - End of Season Unending Quest. Return to Whiterun save is ok Capture Odahviing save is ok ...But as soon as I try to save in Skuldafn...CTD I also get random CTD's in combat. Trying squireoivanhoe's method. - Uninstalled Diverse Dragons Collection, based on other posts, - Uninstalled Convenient Horses, It just wasn't working at all. Loaded my Skulfadn saveafter cleaning, killed the 1st two Draugr and the dragon, tried a manual save (console - save [savename]) and still CTD. Went back and cleaned the two previous saves to my Skuldafn one, Loaded the cleaned save where I have captured Odahaviing, flew to Skuldafn, killed the two draugr and the dragon..... SAVE SUCCESSFUL, both quicksave and a console save (savename) Thankyou squireoivanhoe
