I am not 100% sure, but I think it should work

Can I install this mid save?

I honestly have no idea what VLDL means, lol

Lowkey VLDL reference in title?

I've added some improvements to the mod (listed in change notes); I've tested it, but there are quite a few branching choices in the affected events, developments of which I could have missed, so be sure let me know if you find something weird.

I fixed the oversight where admin vassals wouldn't be branded as traitors.
Also, I will leave the mod as it is for now, because it is so much more compatible, when most of the stuff is handled by events.

I looked quickly into the files, and it seems that "MIV" doesn't edit character interaction to stop war... so it might be technically compatible, not sure about that though, but I'm pretty sure that there would be some "logic errors", like you know two systems attempting to do the same thing.
So unfortunately I can't give a clear answer, you would have to try yourself; and if you do let me know how it goes.

is this compatible with interactive vassals mod?

Quick compatch to the latest update!
I have disabled vassal calling for war and separate interaction to join the war; those are to be fixed later. For now you can demand your vassals surrender through "stop vassal war" interaction, and if they refuse you can join them. Haven't tested it yet in practice yet (but I will in a moment!), so I hope there won't be any bugs.

I just hope I won't be having a lot of stuff to update with the next patch :>

Thanks! That's a good idea, I should write about compatibility; I will update the mods page in a moment, but of the top of my head, I would say that the mod should be highly compatible, excluding other similar mods of course, because even if files in those cases wouldn't overlap, there would be some logical errors, like two events doing the same thing, etc.

These are very good qol changes. Would be great if you disclose if this mod modifiers vanilla files and how compatible it is with overhaul mods.

So, the recent update is relatively big, and contains:
- High crown authority and alliance with your liege will make it harder for factions to press their demands
- You can now select a game rule to join any internal war on defenders side (after the attacking vassal refuses to yield), unless attacker is your ally; internal allies on defensive side will still call you to war, so don't worry you will be notified.
- AI now actually stops it's vassals from warring each other too (It doesn't in vanilla!) I had to do it in roundabout way, but it works...
- I also added some more factors to whether the vassal will accept to stop the war.
If anyone has any impressions with how often AI lieges decide to stop war, and how often AI vassals surrender to you demands, be sure to give me feedback about that, so that I can balance it better.
(Also, I tested stuff, but I might revert to previous version if something happens to be horribly wrong)

Thanks

very nice.

Cool, feedback is welcome, just make sure that you have the latest version, cause I fixed quite a lot of bugs through those couple days (but the mod should be compatible withe already existing saves).

I like this in concept. It absolutely kills me when I'm at the Empire level, I've got my heir, then some random vassal is trying to seize the duchy I gave my heir - I don't get notified, I can't step in,can't enter the war on my vassal's side, whatever else. I'll be giving this a try and reporting my thoughts.

Feel free to report bugs, and write some suggestions.
I will keep the comments open for a while to gather those, but I will probably disable them later, 'cos I might not have time to respond anyway
