Due to a glitch at the church, I can't progress in this mission at all. The first I went to the church, there were two raiders there I had to kill. I did it without second thought. But instead of going on to the next step, it still says that I have to "clear the rendezvous point." There isn't a raider for miles and this problem has persisted for weeks. The update did not fix it. I just want to progress through the railroad quests, but since I can't finish this one, I'm stuck. Please respond as soon as you can.

and have found no way continue the Railway quest line yet. I have 2 raiders inside the church and 1 ghoul outside with some BOS dudes in power armor around the corner.
