In the thread I posted earlier positing a marriage between Isabella of England and Louis, Count of Flanders, I started looking around for who else Louis' OTL wife could marry, and while I was looking at the dukes of Burgundy, I came across how "flukish" both the deaths of Philippe de Rouvres (who married Louis de Male's daughter OTL) and his dad, also named Philippe, titled Comte d'Auvergne (who both died in horse-riding accidents) were. So, if either of them don't fall of their mounts, or even if they do, they don't end up dead as a result of it, how might this affect things in the Low Countries? Especially if it means that the Valois' getting Burgundy is either butterflied away or delayed for a generation.
