This is not generic to all "abandoned workshop" quests; but on this map this one particular quest everytime I enter the game crashes.
The text Deal with Skaths comes up (note that during this game I have successfully already completed a very similar quest); when I select deal with skaths; it brings on the skaths and then crashes.
I have a save; I've tried this 10 times with same results. If someone at stardock wants the save drop a note.
