Realm of Chaos changes original versus current version

[Still River]

So I have finished original version of Realm of Chaos campaign for Cathay almost 2 years ago. Could someone please tell me what has changed since then? I remember rifts would open all over the place back then. I now play Kislev Katarina. Not sure how does campaign victory progress advance in current version of Realm of Chaos?

Patch notes[www.totalwar.com] for you (actually two of them[www.totalwar.com], lucky you)!

Rifts still open every where but now if you build the watchtower building in a settlement then no rifts will spawn in that province. I believe the negative traits you get from the chaos realms get removed instantly after leaving the realm instead of having your lord wait in a settlement building for a few turns to go away.

I believe those are the only things changed everything else is the same. Some new factions have been added to the map due to DLCs since then and more regions were added to the map as well.

You can now stop rifts from spawning with the correct building. (the one that gives undercity detection) Just 1 in the entire province stops a rift from spawning there.

You now lose the negative trait after killing the daemon with the soul. So no need to stay in your capitol for ages to have it removed.

The Ai no longer auto completes the Tzeentch rift in 5 turns.

You can intervene a AI that has all 4 souls, removing all 4 souls from said AI if you beat them. The Ai cannot do this to you.

Many thanks for your answers everyone.
