I don't see why this would be necessary the Elvenar event buildings become less useful the longer you keep them and they cant be updated yet
So if they are in storage to long they wont have much value other than visual
But that is exactly my point....if you can store and retrieve at will, it hurts the puzzle aspect, if you can only retrieve into the no bonus area, that fixes it.
Event buildings lose value over time, but are nice to look at, so being able to display them would be great.
1. It would let you keep pretty buildings without harming your efficiency.
2. It wouldn't effect the "sliding puzzle" aspect of the game, since it uses space separate from your city expansions.
3. If you play for multiple seasons, you can decorate seasonally.
4. If blueprints allow you to upgrade event buildings, it would tie in perfectly with event storage as described in my post.
5. Players visiting you would be able to see your achievements.
I don't think the FoE system works in Elvenar, since a 12 month old event building here is probably really inefficient.
If there was an event storage area, and the only way to bring it back was using blueprints, and that also brought it back upgraded to your current chapter, that would be cool.
