Perhaps when the Child Emperor asks to get back his crown, the regent can refuse and there can be war.

Yeah I think it's possible, but how it's setup, they have no access to troops or anything so they'd automatically lose any war, I have some ideas on how to implement it. But focus right now is figuring out how to update the workshop, until I can find someone to guide me through that not sure this release will last on the workshop.

You need to make this possible for all duke tier and up titles

Lowest I'll go is King tier but first the mechanics need tuned, not sure how reasonable the ai decision making is and how well the consequences work.

This is not a technical suggestion, but I didnt find this mod easily, I came upon it by chance at AGOT forums, how about making a thread for it at paradox forums? since it will get much better visibility there. With the community mod expertise, others may also find ways to build upon your good work here. https://forum.paradoxplaza.com/forum/index.php?forums/crusader-kings-ii-user-modifications.682/

I felt rather dismissed from there when I started out modding and asked for help with getting some stuff to work. So I don't go there anymore. My mods are readily available and (hopefully) well described, here, the agot forum, as well as tested releases of versions on ModDb. This one will go up soon, I wasn't sure about the war script but seems work so I'll add it to my collection there.

I can feel where you coming from, my modding questions are still unanswered there too. -___-

It's a big part of why I hang out at the AGOT forum and put up mods there, Blackninja was readily helpful with answers for my questions on modding and is a big part of what allowed me to develop enough to make my mods into what they are. So I do what I can there to pay for it and help others with their mods.

Hey Sin, enjoying the mod so far. I have even been tinkering with allowing the AI to assert regency itself, and it is working wonderfully so far, as it allows a new sort of power struggles within the realm as all big lords can vie for the position of Lord Protector. However, my only gripe is that whenever one of the vassal manages to seize the position, it reverts back to being non elective, and the new holder will become "King" or "Emperor" etc.

How can we make it so that as long as there is a legal heir (with the X protectorate title) ,the said primary title would continue to remain elective? With the different holders continuing being Lord/Lady Protector, to reflect their precarious positions as the non-legal holders of the title. This is also a fun way to show a realm, where power lies in hands of powerful vassals.

you'd have to disable the succession laws for regent titles
