I know that Titania claimed Italy after the First Fall of Atsnia, and then when Watcher bailed on Titania he gave Titania to you, but I don't think I included the claims in your inheritance back then (Oops if applicable). When you became involved in the Second Fall of Atsnia, it only had the Northern French land which you now posses.
Either way, Yaslovakia's not just claimed but had Italy annexed for a while now, and by rights you've had ample time to dispute his claim.
EDIT:
SWAT, I'm going to guestimate on where you're putting the DSR refugees. Holler if I didn't do what you had in mind.
ONE LAST EDIT:
Vierte and the DSR should provide a nation post so I can add a link in the first post. Thank you.
