Hmm so 0-1. The thing is, it passes my validation happily. Do all of the color entries give you errors, or just a few of them?
RE holder_scope: The validator currently treats this as being in a character trigger, in which holder_scope wouldn't make sense. But that may be an issue with how it treats PREV. Could you tell me which scope the PREV points to (i.e. is it most_participating attacker, on_success_title, or which), so I can make sure it is actually pointing to it?
Same thing with usurp_title, can you tell me where PREV points?
It seems strange to use any_vassal within a title scope (why not do holder_scope={ any_vassal = {...} }) but I guess it works, so have added it.
I have added held_title_rating and mercenary.
Thank you for all your help
