It works in the app, but not in the game. I have a Hyur Conjurer with 'When accompanying someone of a different race, tactical ability is increased by 10%.' This works fine and the results are good when there are no other Hyurs in the deployment squad. However, when I include my Hyur gladiator, the chemistry becomes inactive and I lose that 10% bonus in the game, but the app still is applying it as if it were active.

My squad's out right now, when they come back tomorrow I'll see if I can come up with an example for you.
