So, I finally beat the MQ and am now going to go through and do all the different guild/group questlines.

Among them, I went ahead and continued in the Civil War questline (Stormcloaks). I had completed a few side quests within that questline and was at the point where I was supposed to go take Fort Neugrad.

However, after completing the overtaking of the fort and reporting back, I don't get the necessary trophy for completing it.

I've heard there is a glitch that causes this if I beat the MQ first (which I read about after the fact).

Is this something I can simply load a save before the completion of the MQ and correct or what?

I'd really like to get my platinum for Skyrim and I'm only a handful of trophies away from it.

Thanks!
