MMH5.5 - Heroes of Might and Magic 5.5

Thank you. Thanks to point 4, I manually configured the alliance using MapMixer. It works. Now, if only I could rebuild cities or at least 1 city.

The number of cities and dwellings that can be rebuilt directly depends on the total number of buildings of your faction on the map.
For example, if you are playing as Humans or another faction, and it is allowed to have 3 cities, and there are 3 or more cities of your faction on the map (including neutral ones), then you will not be able to rebuild additional cities. The same applies to each of the dwellings. There are separate limits for each city and each level of dwelling.
Information on where to view or change the limits can be found in the instruction.
