I was wrong about the beast den part. It happens to any room in the save file, some walls work correctly and some do not.

Since it's the same save file where Kasita changed her color, it might be connected somehow.

It's a weird issue, I have no idea what causes it. You have my game save from here https://brightrockgames.userecho.com/topics/1166-after-loading-a-save-kasita-changed-color/

Load it and sell a few beast den tiles near the tavern wall, like on my screenshot. There is only one den and only one tavern, you won't miss it. Some walls work correctly, some not. Fortunately, after you build there another room, walls start to work correctly again.

I suspect it's a save/load issue.

I already did it, read my first post again -_-

Above the screenshot.

Nope, I played Kasita campaign all the time lately. It's not the first time when it happens, I already played this level before, and at some point after loading a save she became green.

Another popular place for lava bathing.

Yeah, after loading a save either all beds are invisible (I reported it here https://brightrockgames.userecho.com/topics/1061-missing-beds-after-loading-a-save/), or, rarely, change positions chaotically while rendering on each other.

Can't they become happy again once you use on them the spell that gives gold, like other creatures? Because atm they ignore it completely.

Even so, I see no reason to disable this option in the home realm.

There is a save game attached in this thread

It's basically the same bug.

I tried it in both C13 and Oberon home realm, with all titans except the new golden one. Disabled steam overlay, changed game speed to 100, turned off logitech setpoint, tried to save then exit and load the game. Titans don't disappear.
