I might be missing something, but I am running into something confusing;

In two of my cities I have two single tiles (next to eachother) of free space in my city's range of infuence where certain improvement icons show up when I try to build them, but others (like a School for example) cannot seem to be built, eventhough the space is there aparently?

Or does the School need 4 tiles perhaps? Is the needed tilesize shown somewhere?

Another thing I noticed is that you really need to think about where you are going to place a city. If it's next to other objects, this will cost you space for improvements. Perhaps quite logical, but I had expected available tiles to 'jump over' e.g. emerge on the other side of a river or such.

My Gilden Empire is seriously hampered now. I have three cities, which are all limited by building space. But before I restart I would like to inquire if it's going to be possible to salvage the game.

All input is appreciated.
