Hello,
Is this a really a planification game ?
How can we plan anything if event like this are not announced ?
Do you remember that some of the most importants buildings upgrades take more than 7 days ?
Why don't you have a minimum 7 days delay to announce events like that ???????
This way of doing thing make people frustrating and think that you are not really taking care of them...
Many have already left...
Maybe that's what you want ?
