I've done all the jobs around the mansion (after having visited all the suspects and completing that part of the quest line). I've followed all the clues you gave in your other thread about what jobs to do Duduie. The only thing I may not have done is a job associated with a 'yellow potion'. Is it a curative potion, a corrosive potion? Maybe it's beaver wee, so I need to do Demolishing the Dam!..?
I didn't think I was that dumb, but I'm obviously missing something.
p.s. in the quest epilogue the sheriff says to do it quickly otherwise the guilty party might get away. I've not traveled all the way back to my home town, but slept near-by (didn't know how long I had to do jobs for from reading other thread, so started with 30 min each, then upgraded to and hour each, hence had to get more energy to complete). Is there a time limit?
