Right but what I think may be happening is that instead of just making the war end as-is it may be forcing the AI sides to make a peace deal that potentially involves sending cities over.All wars end when the Age is over. It's jarring, but so is the whole Age mechanic... something like a thousand years passes in most cases between the end of the previous Age and the start of the next. It's really not the same playthrough, more like a new game with a similar map seed.
