game time bar freezing

Some people are complaining about freezing time bar on my game, and i have actually experienced it. it happens on different occasions, one which is if you are playing a level in the classic mode and you pause and go to the leaderboard, go back to the mainmenu and then back to the level you were before, the time bar freezes and the person can play the game till tomorrow. I've looked at my code and cant seem to figure out the cause of this(note that this happens just once in a while in the game). Anybody with suggestions on how to debug this? thanks

Beaverlicious, i've put up some snippets of the code from level 5 here, for the mean time i've found an unprofessional way around it, but would appreciate a more appropriate solution level 5 code
