stop & go penalty

I recently downloaded ver 5.23 and am having problems with stop & go working correctly
if 1 car goes in to serve a penalty all works well
if 2 or more cars go into the pit the first car serving a penalty will get the sound to go but when the car leaves the pit the penalty is still there,
also if 2 cars are fueling and 1 cars leaves sometimes the other cars stop fueling on their own.
the both problems dont happen all the time just randomly, I never had this problem with previous versions
I will try to narrow down the problem more for you........rick

I made a quick test and no problems
I assume your Stop & Go penalty is generated by a track call, right ?
Also did set your track call to pause the race, stop the cars or start a yellow flag ?
