Been launching directly from TESV.exe since using the UI hacks. I'm too afraid to ever use the launcher now. :(
Well, seems I'm not the only person having trouble with Mount Anthor. There is a quest that requires you to go there, and if you go without the quest, seems killing the dragon causes the game to bug? I'm not positive yet but I'm getting real tired of these things.
That's not so bad :). I had to kill a necromancer in a dungeon the other night, and the final room's door closes permanently behind you. You're "extracted" from the dungeon a different way. Well, that extraction didn't include Lydia. So when I didn't see her outside with me, I crawl back into the dungeon and arrive at the permanently sealed door... great. Open console, "TCL", fly through the door, "TCL", tell her to head on home (she runs up against the locked door and eventually fades), "TCL", fly back through the door, and "TCL" again to head on out. Luckily, Lydia arrived back at home awhile later.
