I bought all three based on the item description in the event tab, was blindsided by the exorbitant cost. That's 12k eggs I can't spend on something actually useful. At least I was able to warn everyone else I play with, so they can avoid the titanium trap.
I've also been told it's my problem for not knowing to go outside the game for resources to tell me how useless the building was. Not by BB, they've not answered any of us, but by other players.
I'm not sure they read the American forums anymore, but it has been acknowledged on the German forums, although not the complete lunacy of the building but just the lack of information that it uses oilseed. If nothing else, this thread serves as a warning for others, but I can't understand why any developer who actually plays the game would have thought this was a good or fair or useful building.
