I am playing the stoarmcloacks line of story, and finally i get this quest from golmar (battle of solitude)
I reach to the city to receive orders from ulfrics, he gives an speech to his men and all of them run and enter to the city of solitude.
Here come the problem, when I enter in the city, there is no siege or quest mode, the city is normal and its citizens waliking by and doing their everyday things while only gulmar, ulfric and me (yes, only we 3) fights without others stormcloacks companion, and by the way, every enemy soldier i kill, i get a bounty.
How can i solve this? i tried with different patch, loading the game from 2 or 3 quest before, even i formated the pc and reinstall, i replace skyrim ini and skyrimpref for ones of a friend of me.
Please someone who can help me with this ugly problem.
