Can not upgrade in new city

My son and I have just bought a new City in castle craft but we Can not upgrade buildings. When we try to upgrade to level two we get the answer that we cannot upgrade to level three before we have level two, but we Can not upgrade to two. Does anyone know what this is All about? Rikke

Hey Rikke, You have to upgrade your castle to level two before you can upgrade your buildings.

I have the same issue, I took a city over and it won't let me upgrade buildings without doing the basics again. I can build the basic buildings but the studies are all still upgraded as they are in my capital city. Eg, to upgrade a building it asks me to study woodworking L1, I go to woodworking and it is already level 3. Is this a bug or new/invaded cities just can't be upgraded?

I recently hasd the same problem. I found that if I reloaded the game a few times and researched everything else i needed to upgrade before I focused on the glitch. By updating the status of the building I fixed the glitch. Just sound like a communication error in the game. Try to update the states of other buildings or research. That should hopefully make the game realize its mistake and fix the problem.
