Thanks for pointing this out, it has now been fixed for the next version.Another problem that seems to come up with megawars is when an independent LP tries to press his claim on another LP, who currently is a vassal. He properly attacks the LP's liege, but this triggers a megawar, which promptly splits the kingdom. As the king no longer has the contested county, the war immediately ends and the kingdom reassembles. This can happen every several months.
