So, I will be restarting my Dark Heresy group after about two months of downtime, however, I can't seem to get the gumption to get any adventure lines set up, and my players wreck premade adventures, by asking the wrong questions (that I dont have answers for) or doing totally unexpected stuff. Also, I cant seem to get myself psyched to GM again, and nobody else will do it.
TL;DR How do I get myself in the mood to GM again?
