I've been trying the download in the description(fix.zip) and adding it to the game files now for a few days. I've been getting a few errors but the ones I put in my earlier post I've realized don't matter because I get those errors aswell when starting the game without mods and the game still works. Now the reocurring error I get is

[2429069.851] UpdateDatabase - Loading Data/Aztec_Montezuma_Expansion1.xml
[2429069.851] ERROR: Failed to release save point.
[2429069.865] Warning: Error when calling IComponentHandler::ApplyComponent.

and

[2429070.959] UpdateDatabase - Loading Data/Poland_Jadwiga_Expansion1.xml
[2429070.959] ERROR: Failed to release save point.
[2429070.974] Warning: Error when calling IComponentHandler::ApplyComponent.

So I check integrity of game files and try again and seem to get one or both of these errors or another dlc's error like these two. I've even tried downloading the fix again without checking the integrity of game files hoping it'll fix this problem and it doesn't work either.

any suggestions would be great because I love this mod and am abit flustered and confused about why I am still getting this error..

I have no other mods enabled except this one.
