The interesting thing about this:
I play on moderate (everything) as Cesera and since 1.3 have noted that AI mobs ignore AI cities and go out of their way to attack mine. This was not happening pre 1.3.
It's gotten to the point where I have founded cities, had the local Mob trash them and return to base. An AI player then runs in and steals the location - and the Mob ignores them, but if I move my troops anywhere near the AI city the Mob comes straight out of the base and attacks my army - it then seems to continue outward until if finds my nearest town and hammers it flat - unless I've kept several extra units in it as a precaution.
I'm finding the new AI changes have made expanding impossibly hard as I can't expand anywhere near mob sites - and now high level spawn sites seem to exist near every possible settlement location. The AI which has no such problem with the mobs then pounds me into to the dirt.
Also noticed that the differing border colours around the players seem to have disappeared - everyone is 'yellow', including mobs.
I'm not sure if I'm going crazy or there is actually an issue at this point, since no one else is reporting it.
Also there's a weird spotlight effect occurring on the tactical map since 1.3 where highlighted squares have a beam of light visibly causing the highlight
