That's awesome. I didn't realize that that already happened.
Then, yeah, it's not really an issue. You just have to plan for it.
The All-star break week hindering your economy should at least be mentioned in the Game Manual on the All-Star Game and Economy pages. That way, instead of it being a surprise, you can just point to the place in the manual where it says it happens. As for the other two weeks when you don't get attendance, that may need to be noted somewhere in there as well.
