A really unimportant bug, but a bug nevertheless, the clock during games displays things like 8:60 or 3:60 instead of 9:00 or 4:00.

It also runs when a player is pushed out of bounds

This should be correct, when a player goes out of bounds or is sacked before the last 5 minutes of the game the clock stops until the ball is spotted at which time it start running. So less time is run off the clock than if they stay in bounds, but the clock will be running when the play loads.
