Its definitly not the uninstallation of 1.08b. Save right after I uninstall 1.08b -> Works fine Save after cleaning this save with Skyrim Save Tool -> Works fine Saves with 3.0.0 installed on either saves (cleaned or not) -> Corrupted If I desactivate the esp and leave the files installed, the problem persists. On the other hand I tried to start a new game, and everything seems to work fine. I ll guess I have to revert to 1.08b :-(. Its a shame because I had it installed since the beginning of my playthrough, but didnt start any quests with it yet. Thanks for trying to replicate the CTD anyway, appreciated :-)
