The problem is that it usually freezes because of the AI; that is, some cities, due to events, can bring in a certain amount of gold every day/week/other period... as well as monsters (like the Tower of Rissa, for example).
By the way, Jedy Story has this feature, and the AI's growth is faster than the player's.

Is there any priority in the Russian translation over the English one?
I can recommend a couple of maps specifically in Russian (besides Paragon and Jedy Story, I don't remember any others where Russian is the original language).

There is no priority; I play with both Russian and English maps, the main thing is that the map is interesting. By the way, sometimes there are differences between them. In the map "Insomnia," unlike its English version, "Insomnia," blue is an ally. This may also be observed in other maps.

I played German maps; it's hard to understand the description :D, but I defeated the AI even without knowing the language. I haven't tried Chinese maps yet; I downloaded a couple of maps but haven't decided yet because of the stories about how difficult they are.
