@MuttersomeTaxicab: I'm glad you're enjoying it. I'm trying to work on a new segment, but I really can't figure out this Trade Depot thing, and that's kind of a game breaker.
I know this may be kind of late to answer your question, but I had the same problem last night and I had to find a solution. Hope this helps anybody else who might be struggling. Now move on to the next thing trying to hinder the progress of the great dwarven race! :)
