Hello! I found what I suspect is an oversight, but still wanted to let you know. Minerva says that Ella won't show up at night because she needs her beauty sleep. Maybe so (she clearly DOESN'T need beauty sleep in my mind) but, she was willing to talk to me and do business at late night. Possibly because it was first time, but it seemed weird that she would be unavailable at "night" and available at "late night". I did it just excepting there to be a message "return tomorrow" and she just treated it as normal. She did say "shouldn't you be asleep by now?" before letting me craft a couple of charms so...not sure what's going on with that.
When I went through saving Evelynn after DL the latest patches the uncaught error about missing a header didn't show, so hopefully you found that bug and squashed it!
