You can change Jacks tokens for gems. On the other hand, try to get alliance favors, that can unlock you eventually library, and back to school. But be prepared to assist progroms.
I`ll try out, hope, it will bring me more near the research, for that is halted at the moment.
Without the precious hints, I would have done the bounty thing.
That mod is just great, not intuitive in every situation, but hell of fun.
EDIT:
Yeah, got the library! What misterys will this reveal to me?
I have just built a slave taskmaster. What is his use? I read the text, but didn`t gain any information out of it?
