The compatch is outdated. I've updated the description with some info.
Basically people who are not me and much more knowledgeable than me (I'm not a real coder I literally just looked at base game files and reverse engineered how stuff works from there) have been continuing + expanding the mod in the background and plan to do a release.
Currently they're only giving playtesters the mod, so you'd have to agree to reporting bugs, clunky things, un-fun things, etc. Idk what's in their version of the mod as I haven't played CK3 in over a year.

I'm having trouble getting this mod to work. I have both Rise of Eldia 2 and the compatch and it just won't load the mod but just base game CK3. Does my game need to be on a specific patch of the game or is it something else?

where is collosal spines innovation, titan walls building?

oh aw man no eldians sad

There's no Eldia on the map. The AOT world is just ours flipped upside down, and Paradis would be Madagascar, which isn't on the map.

I usually play on that island with the cool gold mine. Or Iceland.

were are eldia on the map?

My ex wife ripped out my kidney and is holding my favourite dog hostage.

Yesn't: if anything is broken tell me and I will fix it. However, I won't be adding new features, unless said features are made by other people and then just integrated by me.

still working on it?

I love the mod even more than they love the mod

I love Emilia.
