Event 90008 in EEP/Events/post_byza.txt, the Genoan Land Purchase, has no date field and is not triggered by any other event, so the whole sequence (90008, 90002, 90044/90045) never happens. Since it has trigger conditions, it'll also need an offset and deathdate if it's to happen at any time other than the first time it's checked or after loading a savegame (like with 40063, Cessation of Crimea).
