Unable to get my last poi...
Have you checked the cities? (I know DR had a new one added somewhat recently.) Gotten the Chantry of Secrets PoI? Looked at the list of all PoIs added since game release?
My last two were the Chantry hideout and my personal last was the new one in Divinity, I made my guildies go through Arah twice for the poi I missed but it was in Divinity lol
