I'm experiencing an issue with B04, I can't upload my new personal best time I drove a couple of minutes ago.
First I got a huge error, then I tried again and it says "replay already exists". I also re-validated the replay.
I reported this yesterday in private forum, the error looks like...
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Best thing to do right now is not post replays to improve your time, until we have fixed this issue.
