I've had that prob too with the resources, I think it only happens when you activate the resource options after the level is already loaded, actually playing the mission. When I activate the options while still on the menu screen, before loading the level, it works fine.
Its the same here xpgeek. The trainer works fine if i activate the options before the level start. But if i activate the option during the level, theres like 30% chance of the trainer not working properly. Its just a small problem that i experience.
