Do you use Client Rulers and recruitable Generals?

Easier to fix than you'd think, literally just delete that section from the script. Takes a minute or so if you click where it starts, hold shift, scroll down to where it ends, click there and press delete.

Now changing the Interloper business is more work, I didn't bother with that.

Basically the same: Open EDCT, search for the triggers pointing to that trait and delete them. No one should get the trait now. (not save-game compatible!)
