Please note that the update/maintenance that brought in the football event has also corrupted the mails sent by the system during the Valentines Event, all the message headers are now lengthy "object not found" type messages, as are parts of the main body of text within the message.
These were the mails generated when we drpped/received cards on the flower farms, and the exchanges of flower bouquets, so that update has corrupted the database of actions essential to that event.
Don't know if you're now reallocating resources on the fly from event to event, or if this is another unintended knock-on where a change bugs something that was working before, but left unchecked this is going to cause the merde to hit the fan in 6 months time when you reintroduce the Valentines Event.
