Waiting for a new season

It looks like in this case it hadn't generated. I've just added it manually.

Thanks for letting me know, Simon. I've just generated a new one manually. There is obviously some kind of bug when it comes to generating new seasons, and I suspect it's just timing out executing all the data becaues it's a huge amount of data it has to process. It's something that will be looked in to anyway.

Sorry to hear that. It's good that it's a recurring issue for particular leagues, though. We may be able to track down the cause from that.

I've just changed the way this is engineered in the hope of preventing any recurrences of seasons not being generated in future. It was very rare, but a significant issue to any league it happened to. The first proper test will be in a couple of hours.
