Getting a mod folder recognized

:help:

Hello,

I am having a problem my getting my modified Crusades campaign folder recognized.

After having to uninstall and re-install the original Crusades campaign because it didn't like my first mod attemps, I copied it as mycrusades under the mod folder. So I currently have two directories:
mod/crusades
mod/mycrusades

The original Crusades campaign shortcut works fine. However, the new shortcut with:
"C:\Games\Medieval II Total War\kingdoms.exe" --features.mod=mods/mycrusades
instead starts the original grand campaign!

What else do I need to change to run my modified campaign mod/mycrusades?

Note: I didn't add the --io.file_first switch yet. I'm trying to get mycrusades recognized before proceeding further!
