Timer does not update in Vehicle Game

When trying to test Vehicle game, the counter did not increase as time elapsed. This prevents being able to test if the lap function is working.

Tested in 4.13.2 CL 3145013 and it was working. This is a regression

1. Open Vehicle Game in 4.14
2. Press PIE
3. Wait until the countdown finishes and observe

Result: The timer never increases, and stays at 0:00.00.

Expected: The timer increases in real time.
