Ok, the seasonals deadlines are 3 in the morning.. Does anybody know what happens if you have opened the challenge, can you complete it ?..even if the clock turns 03.00 before you finish the race.. ?
Im sure you will finish it and recieve rewards as normal due to the fact you have already loaded the event. If you can get in it will tell you at the race or series selection screen. (try chooseing GT ACADEMY round 3 in in the us, or try one of the other expired ones and you should see where it stops you. IF you are past this point before the deadline I would bet you can race it)
A few weeks back I forgot about one of the Seasonal Events which expired at 10PM local time for me. I loaded it and started racing, had a few crashes, tweaked some settings, etc. By the time I finally won it was a good 10 minutes past 10PM. Just don't exit to buy more parts because you will not be able to reload the event.
