After 1 year I thaught you would have fixed it but apparently not... I've used 50 hours worth of speed ups and then it came up with a message saying "You don't have anymore of this item" so i though hmm ok I must have used them all...backed out looked at the times on the construction it hasn't moved, closed the game and 're opens it to find the times was still the same and I lost ALL of the speed ups I used
