That might be. In one storehouse I get food, in the other tools and in the third stone. When I check there was stone in all of them, I, however, used first the trainer for the super-storehouse that might have confused the trainer.
As long as I can get it to work with stone I am not upset about getting food as well.
This trainer works perfectly and the game does not crash anylonger but runs smoothly as its should.
