Mirjam and I are as well always busy with details so join the club haha ;-) But indeed; we try not to increase creativity!
The peacetreaty with the Hittites occured indeed in the later years of Ramesses reign; in the years after the Battle the circumstances weren't too peacefull yet...:-P But hey, we can deal with that!;-) If you are a princess, what about an exchange first, sort of an good gesture from the Hittite king to give his daughter to the temples or something like that, years before the marriage with Neferure? I'm just saying something, maybe you totally disagree with me, but I'm sure there's something to be found. We don't want to wait 30 years for you *LOL*!
