So Jahiera left the party, and came back a few days later. She tells me that I need to go to the Harper Hold. I do, and the front door is locked and the NPC from the earlier quests isn't out front any more (I didn't kill him or anything). I tried coming back later - still locked. Just patched the game (I reinstalled it just recently after like 6 years of collecting dust), door's still locked. Am I doing something wrong, or do I need to cheat to teleport myself to the roof or something so I can get in?
Not sure if anyone can help. Try to patch it with the latest official patch and then use one of the unofficial patches to fix yet more bugs in the game. If it doesn't work, then you probably have to start the game over or ignore that quest.
