Having a look at some of the code around this game, the blue prints are extremely buggy, sadly because its all hard code it can't be changed by a customer. Its going to need a patch and there really should be with the awful mistakes in there, horrendous logic on how they have been primed.
Basically if you play the game a certain way early on, like if you test a blue print and then decide you don't want it, this bug will happen.
It will be your deleted structure will be on the blueprints menu forever and if you start a new one the blueprints menu will be locked to the old deleted structure so for example. If you remove the soccer stadium, remove it and then build a base ball stadium you will won't see any options for the base ball stadium but it will ask you for the some tokens as the old soccer stadium.
You will then see the new stadium building up in time with this menu but it will mean once its finished you won't get the completed graffic, it will get stuck looking like a building site. Its an awful bug. terrible coding and bad choices just like the registration process here. Capture code and a math question? Pff come on next these forums will be asking people for their blood type.
