There is a bug that I introduced while fixing a different bug. You should not be able to see foreign cities' anger counter from whipping/drafting, but in removing that I accidentally removed the happy/unhappy levels as well. This will be fixed with the next version (I can post you some code to fix it when I get home).
Are you two on the same team? When you open your partner's cities, do you see the number of turns of unhappiness that will occur by whipping when you hover over the whip button in the lower-right of the screen?
EmperorFool,
Thanks for the prompt response! Wow, I had no idea that there was this much support for this mod, I honestly posted that message expecting to just have to suck it up. =)
I'll check this evening if/when we get a game going for the whip unhappiness.
