Enemy troops on the planet? Do you mean during an invasion? So I assume you've also modded the ground combat so that it takes longer then the stock 1 turn to finish?

EDIT: Ooooo, if that's the case you could really have ground combat that went on for years. Since the planet isn't rioting they could keep pumping out more troops, and you could keep dropping reinforcments from space. Although, does that only work in turn-based? Will your troop ships drop troops on a planet that is in the middle of an invasion in simultaneous-mode?
