In Liberation of Skyrim im part where im asked to liberate Haafingar. I go to Stormcloak camp in Haafingar and Galmar Stone Fist tells me to attack Fort Hraggstad. After the battle i go back to Galmar but he only says that "We are ready to take the city" and gives me quest "Battle for Solitude". But i cant finish previous quest "Liberate Haafingar" because quest arrow just floats above Galmar and he wont open dialog options.
I can go to Solitude and start battle there but Galmar isn't there and just stays in camp refusing to talk to me.

Any way to finish that quest? ( Platform: Xbox360)

You can't finish "Liberate Haafingar" without taking Solitude. Solitude is the main city of the hold called Haafingar. The quest will be finished when the battle of Solitude is done.

oh...Well that makes sense. I didn't remember that Solitude is capital Haafingar. Thanks for the help !
