I an unable to complete the first mission in Concord, "When Freedom Calls".

Most of the raiders were killed already when I was given the mission. I did kill the deathclaw and obtain the power armor. However, the quest still says that the town is not cleared. I am unable to find any other raiders to kill and I have explored the entire town and every building.

Should I just stop playing and wait for a patch? I don't want to start over and lose all my progress so far.

I find it strange that the first mission of the game is bugged...

Please help!
