Well, I really didn't want to lose out on any quest from these Jarls I had not already done nor did I want to travel to Solitude to get quest from these Jarls, so I loaded a previous "saved game" and held off on completing the Civil War quest.
Fastforward a couple 100 hrs of gameplay and I go to complete this questline and now I get to Solitude and face General Tullius and Legate Rikke and I can NOT kill them, talk to them or force Tullius to surrender!
The same dialouge happens with Ulfric and Rikke and she attacks but I can't kill her. She just slumps over in the default "I'm a main character who can't be killed" slump and then gets back up. I do the same to General Tullius but I can't talk to him to get him to surrender. Plus all the doors are locked so I can't leave.
Also, since I've done all the other civil war quest and "triggered" the final battle on Solitude it is completely locked down. It is in it's "battle stage" with Ulfric and the stormcloacks waiting outside the gates, so I can't fast travel to it, I can't go in, there are no merchants to sell/buy from, it's completely useless!!
Can someone PLEASE, PLEASE help me! I've invested way to much in this amazing game to lose Skyrim's capital to a stupid glitch!
