This event is really easy to complete. I have now 600 masks by building civic buildings and selling it. Coins is not really a matter since it can't buy diamonds. I have 600 thousand coins and nowhere to use it except building and rebuilding. But the problem is that after finish it I'll have no more inventory slot which means that I can't fulfill the demand of the next new expansion. Greeting every citizen or delivering every entertainment order may probably give me a certain item that I can do nothing about it but eliminate it from my storage. I have now 51 tripus 51 shovels and 43 raws with only 165 slot in total. If I eliminate any one of theses three kinds of items I'll lose the total number of them. And furthermore any two of theses three kinds of items are useless when I have not the last one because they work together to make new expansion. So when my storage is full , the only way is to remove them all. It's so desperate. To prevent getting more items I have not delivered any orders or greeting any citizens and focus only on the broadwalk orders since a month ago when I was fully expanded. Now I have to do this unless I ignore this event. I've been waiting so long for the new expansion but now this event makes me feel that it's the end of this game. If I can make some use of my shovels tripus and raws in any other kind of event it will be much much better and makes this game continuable.
