Wars of the Wizards 2

How can we distinguish the starting town from a village that the AI has upgraded to a town?

Maybe, by looking at the template to see where the starting zones are? Of course, many people aren't very good at template topography (and I'm one of them), but if the question is controversial, you can refer to the Arbitration Committee, for example, and they can do anything with it - they can analyze the save file and figure it out based on the template. The question will be what to do with games where a library was built in the wrong place (even if it wasn't intentional): technical loss or replay?
P.S. and yes, logic still applies: if you're already playing on week 2-3, and there are only golems or something like that built there (without municipalities and other things, because that could indicate that the AI is developing its economy), then it will also be clear that the town is not a starting town. But following the template will be a much more reliable and accurate way.
P.P.S. it's not often you see an AI building a tower with a secondary tower and building it as quickly as possible :D
