I'm sure I'm not the only one who has run into this?
I completed civil war quest line. Spoke the General after, all was good. All lines completed.
I then proceeded to complete many more quest lines, including main quest, dawnguard, etc... so Several Weeks, if not Months have passed in-game.
However, Windhelm is still stuck in the burning-wreck mode, with all the doors being unresponsive (except for the palace).
The palace has like 2-3 NPCs.
I had the issue where the civil war music wasn't dying down, but I removed that via console. However, I assume something else is stuck that is holding up windhelm from just... moving.. on!
