THanks Guys! I just wanted to be sure it was 'as designed' (as a software integrator, I use that one all the time!).
Anyway, CLINK was right on. The 'Great Rebellion' happened after my Daiymo was sliced and diced! I think everyone is right on this one but the 'trigger' was the death of the Daimyo even though I had heirs.
Thanks!
