So, in the quest "Battle for Solitude" in the Stormcloak questline, I encountered a glitch that pretty much messed up my game. I play on Xbox 360.
In the quest you're supposed to protect Solitude from a siege, or attack it yourself (Don't know which since I pretty much skipped the siege part by accident).. Somehow, however, I managed to get into the city before the siege started, killing all the imperials in the city and in the end, killing general Tullius. Then I listened to Ulfric's speech and left solitude.. Now that save is stuck with the combat music playing ALL the time, and Solitude is on fire from the outside.
This also messed up my Dark Brotherhood quest "The silence has been broken", since Astrid refuses to talk to me before I "End the mess I started in Solitude"
