I have the same problem. Anyone else thinking that maybe they are having a traffic bug so people will spend $9 on the airship? I know you guys said it only transports tourist, but i bet more people are buying it trying to get this bug riddled game to work.
The problem is actually any module with units count as 2 modules. example power plant you can normally have 16 panels, but with update 5.0 you can only have 8. Bus stations you can normally have 8, you can only have 4. schools go from 4 to 2. this makes this game almost unplayable. I have disputed payment of this game through paypal because when i buy something i expect to be able to play it. Especially after 5 UPDATES. WTF EA, this is why people say you suck.
