exactly it was a bug , therefore for the bug to be fixed we need the attendence and money we should of got.
its not even remotely fair for you guys to fix the cause and ignore the effect
You do understand that there may be no way for them to know who had their ticket prices set on time before the last ticket price update. Therefore, they would not be able to re-calculate what revenues might have been. Yes, it stinks terribly that some are losing out on the income, but if there is no way to know that a manager had their income changes in, there is no way to know.
Another variable to consider, if there is a change in ticket prices, there is a change in attendance. All those would need to be recalculated and all those records updated as well. This may not seem 'fair', but it is a much larger issue that just recalculating revenues at a 'new' ticket price.
