From 1.18 I removed the part of the original mod that needed to be updated with each patch and kept only the Defines change, so it will be compatible with all future versions of the game from now on.

Is there a reverse version of this mod, where unpassible terrain is never filled?

@heliostellar
I don't think it is related to my mod, as the mod only affects large impassable provinces. Try disabling the mod and see if the issue still appears; it's likely a vanilla map glitch.

I've noticed a slight bug (https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3539818879) The mountains between Fars and Hormuz are colored red, which is my map color as the Empire of Tartaria, even though Fars is held by the Caliph (green) and Hormuz by the Saffarids (also green). While I have Hamadan as a vassal, I do not have any duchies that are close to it.

tysm. Idk why it isn't in the base game when they do it for so many other areas

I'm not sure I understand your questions.
Before picture = Vanilla
After picture = Modded

Do I still required to use this mod ? or have any change did from vanilla ?

Why the devs don't already do this baffles me. Hopefully in the next DLC that's coming they'll implement it. Until then, you are a godsend.

:Blushing:

I love you so much

Updated version to 1.14.

Sorry, couldn't color that one.

Could you make the wasteland above russia to mongolia also colored like it was in ck2. Thanks!
