To add to the frustration, when you are trying to keep special items for something your storage gets smaller and smaller.
I'm glad i have built all the Parisian, Tokyo and London buildings i'm going to build as i now don't need to use valuable storage space for these.
It's still annoying that i have to sell most of my storage building items because i want to expand my mountain and i really don't want to sell the land expansion ones because as you say, they do take a while to come by.
