I am afraid we are not aware of any changes at this time.With this event (as well as the upcoming Fall event)...regarding the bonus prize buildings obtained through the "event pass" (Forge Fountain and Cobalt Blue Lagoon)...the 1200 (1800?) diamond cost is pretty steep...especially considering that they "expire" after a few days. WTH?
I'm a collector and have enjoyed getting all the possible buildings...but even with the random diamond rewards from recurring quests (and with the diamonds I occasionally harvest from wishing wells) this is quickly devolving to a point of spending diamonds to get special buildings vs. spending diamonds to get expansions in order to place said buildings. Something's gotta give.
I can begin to sell wishing wells to make space but that's cutting my nose off to spite my face. Yeah, I've dropped a little real world cash for diamonds on occasion but it's gotta be worth it and tiny buildings that expire after a week and revert to a dilapidated visual state are NOT worth it.
Is there some mechanism planned for the future where these buildings can be reactivated (without spending additional diamonds I might add)?
