I found a few bugs, strangely both involving Gutter's Cove
When Mina and the Mercs are arguing, and I choose "Capture her" all it does is put her back into Gutter's Cove, playing the same scene of her with the guards.
Also, even though I have Cooch as a captive via recruiting the Mercs, if I go to Gutter's Cove I can still find her there for "Pick off one of the townspeople."
