It re-checks for the 50 ticket count every 2.5 minutes and if anyone joins or leaves the server, to ensure that it doesn't miss the window before the level changes (tickets can go fast with a large server). If 50 tickets is too early to change it even on a nearly-full 64-slot server, I could lower the threshold.
Had a game crash when it got below 50 tickets. Went back to work so havent gone back to see if I can repeat it.
24slot server: sittingduck
Me, I was attempting to get the pop started, weird yesterday server full from 9am till after midnight, today empty. Anyway, empty server gives me chance to practice flying, so I capped all 3 points and then practiced flying jets and heli's. was flying chopper when it my tickets got below 50 and then wham game locked right up and kicked me. My client froze as well.
No idea if this is related to your project but wanted to give ya an FYI.
