Okay, where should I start... The Road. It very obviously goes -through- the city rather than -to- the city.
Second is the Villa's. They began overlapping with other buildings, (Look at the left side,) after auto-upgrading from Houses
Next obvious one is the Palace being cut off by the forest...
And last, and by far the least obvious, would be the Spell Point bar at the bottom not filling up.
Four for the price of one! =P
