Mod Saving/Loading Issue

Alright, so as instructed, I downloaded a mod (Pillars) from the in game browser and everything loaded and played as usual. When I saved it, I noticed that there were no other saved games to save over.

Noticing this, I simply assumed that the mod just needed to be saved anew every time. When I attempted to load up the game again it said something along the lines of the scenario was not compatible with the mod I had currently loaded. So I unchecked the load scenario, restarted the game, loaded the scenario and the load screen said the same thing. Then, I restarted my computer, reloaded the scenario, made sure everything was enabled from the in game browser and...

Still incompatible... what am I doing wrong?

EDIT: This is a consistent error with all mods I download. Does it have to do with the map maybe?

Update: Problem still persists. If I am doing something stupid just tell me and everything will be good

Many Mods that include Civilizations are broken at the moment b/c of the patch... this is actually because Faraxis cleaned up some of its unused code... and many of us modders used Keal's guide to make our civs and his example included the now obsolete tag. You can find the "temporary" fix here:

I'll be releasing a new version of my mod in a day or so to address this issue and make some other improvements to my Portugal mod.
