I have a problem. why not raise my level of Alinza if I donated 400k in gold? As I raise my level of alliance? Where I can find information about the partnership? (Advantages, Disadvantages)
When you donate, then in donate main you must press upgrade button.
Have a good time.
What is gained by having a large alliance?
you can chat with more people, get a higher gold boost, and, in a later update, get unit boosts
