Everytime clicking on some game action like "work", "train", "eat", "relax", etc. the game counts the click twice.
Examples: instead of using one T3 food gaining 3 health point you eat 2 T3 food and gain 3 + how much ever left. Or you train at gym your strength, it is automatically trained twice. You do not get a message, but you can see it on your action points left.
