Where do I begin. 1.3 is an utter mess. I would STRONGLY suggest to stay away from it if you haven't yet.
Just some major issues, not going to include the hundreds of minor issues:
I have broken countless saves. Every time they release a patch it breaks my save. I have had to start over three times and at some point all my saves will break, it is just a matter of time.
I have my own empire and for some reason now it takes MILLIONS of gold to recruit heros. It was not like that until recently. And once you do recruit them, they leave shortly after even if I boost my raiting with influence with them to 100.
Half of my encyclopedia is broken. Wanderers, for the most part, have no stats. My children, when they get old enough, are stuck at HOLDING forever. I cannot bring them into my party, I cannot find them where it says they are. I cannot make them governors.
I have not changed my mods. I have running almost flawlessly since "launch" with my mod setup which is like 5 mods, nothing crazy. 1.3 broke everything.
Oh and cities around the map (this sounds like it is intended) never have more than 10k gold. I have to go around the map after a battle just to sell all my stuff.
1.3 is broken in so many ways. I'm glad they have fixed the battle lag that was happening, but everything else is a mess.
Absolutely nothing good came out of 1.3. It broke everything for me and for a lot of others as well.
Fun game until this patch, tho. Why it was released, even for public testing, is mind boggling and lazy. Test your stuff a bit more instead of rushing out a patch that breaks everything every two days. Do once a week patches and test the stuff internally a bit more. All of this stuff could have easily been found out if you have your internal guys just play for a couple days.
