Oh i see! I never triggered the shoot Florence event until just now, thank you! I got the last endings I needed. The Jed and Florence ending might've been the 6th one, I think? But I got them, thank you again!
Regarding the Jed ending, I still have no idea why it's not working, then.. I know the ending has something to do with magnolias death, but I'm not sure what the problem is.. I'm sorry for not being much help on that!
