town visitor event - double points dropped?

I think there is a problem with the town visitor event - considering the time delay between the time you sell the goodies and the time you collect the money/exp.

I was looking forward to getting the last visitors in town before the 2x exp event had run out - even to spend the diamonds to get the train earlier so I could serve more visitors. However the minute the event ran out, all the visitors THAT WERE BEING SERVED already have dropped to regular exp points. I don't think that is fair. If I am selling the blanket to the visitor at half price and expect to get 1000+ exp for the trouble, I want those exp!!! I don't want to be counting in my head if I will have time to collect, or if the visitor will still be served when the event runs out. I think the bonuses should be fixed at the time when the player decides whether to serve or send away.

We are not getting extra points when event starts for the visitors already being served - fair enough, but also being robbed of the bonuses on the other side is not fair.

P.S. same thing happened on the first ever town visitor event, but I thought it was a glitch that time. it's not being fixed so far

This happens for all events. Like truck, the sheets show double stars or coin until the second the event ends. The sheets revert back to normal. Sort of the same concept. I am level 132 and hit two or three mid-level plateaus before it ended, much faster than normal.
