From john the fearless, philip the good and Charles the bold, they all distanced themselves from the french monarch.
So? And with all that distancing the Treaty of Arras yet still historically happened.
Maybe Charles the bold did not distance himself THAT much because he was only 2 years old when the Treaty of Arras historically was signed... ;-)
Why would you even contemplate giving away lands, its not as if BUR could not defend itself.
Please read through the entire event chain of the "Treaty of Arras" before making such comments.
BUR does not simply "give away" lands. FRA and BUR cede several provinces to each other in the Treaty of Arras events and FRA loses cores on several provinces historically held by BUR. Historically FRA acknowledged a lot of BUR´s grivances and claims in turn for BUR´s accepting the current french king as the rightful king of FRA.
In regards to treaty of arras , there should be a trigger to sleep this event if in event move capital to lowlands is not taken.
No. If BUR ahistorically choses the b option to have their capital stay in Dijon they don´t concentrate ONLY on France but concentrate more on their french lands. Chosing A ( the historical option) is similar in that they may concentrate MORE on the Netherlands, but not entirely as they still tried to conquer the lands connecting their provinces.
That however is no problem at all, as the Treaty of Arras event chain only triggers if FRA and BUR are not at war for the not fully 5 years in which it can trigger.
So - be at war with France and the event won´t trigger.
Or to put it more gamey: If a player choses b (stay in Dijon) he can consciously pursue the french crown and stay at war with FRA (to prevent the treaty of arras event from ever triggering) OR simply chooses B again in the arras event - it´s not that difficult to do.
If the AI by random chance chooses the ahistorical b choice to stay in Dijon then there is no problem that it goes back to the historical course of events with the treaty of arras events. I don´t think that an ahistorical choice in one event should prevent a later important historical event from happening if the situation is similar to what it was historically.
Your relation idea is basically flawed because in the game we have relation creep, everyone by default start with a plus 125 and then usually everything has more positive relations than negative, both in country events as well as random events. Relation is not balanced.
Having a core on the others provinces like FRA and BUR have will slowly let relations detoriate.
Oh - and perhaps events like on the bridge of Montereau in which the monarch of BUR is killed and DAU-BUR relations are lowered by - 200. (DAU that later becomes FRA).
However if relations is not the best trigger to use how about the "truce" trigger or about a countrsize check?
e.g. in the FRA event that starts the Treaty of Arras sequence a check that BUR is smaller than say 20 provinces in which case BUR would not accept the the historical treaty?
Edit: Something else that came to my mind. If BUR selects the ahistorical b option to stay in Dijon and reaches the death of Charles the bold events - doesn´t that mean that the command to cede the province in which their capital still is would not work? And so that Spain would get Bourgogne and so a province more than it should?
Should we add a command to move the capital to the Netherlands in events BUR 137012 a choice?
