upgrading fortifications
There seems to be a problem with upgrading fortifications.
Towers are fine - i can highlight a tower and i have the option to upgrade them at will ... the cost seems proper
Walls and gates are an issue
You are not able to highlight a gate or wall to upgrade - you must go through the build construction/fortification interface
to purchase a level 6 gate for a spot with no gate is 1500 coins...the cost to purchase a level 6 gate if you have level 5 gates built is 1500 coins
This does not seem right
Am i missing something?
What am i doing wrong?
