My journal shows the Adeber part of this quest is not completed (the other two are). However, I did find him, I took his journal, it's in my inventory, I read it, I reported back to the mage's guild, they're sad. It still shows it's not completed. Am I missing something or is this a bug? I've researched it on the internet and the internet thinks I should be done. ?? I really don't want to abandon, because this quest goes all over Tamriel and is a huge pain.
