Same thing's happening to me. I made a ticket asking why that's happening. I'm assuming the timer is busted. After mine hit 0, it started counting backwards. I know it's not from me doing anything, because if i sign out of GTA with x hours on the timer, when I sign back in, the time that has elapsed since I signed out will be added to the x hours I left with. (Leaving with 10 hours, coming back three hours later with 13 hours.)My cheater pool time keeps refreshing but its going up why?
