At the end of the dialogue for the "Herself" topic when meeting with Kaede on Myrellion, I received the error "ERROR: attempted to extend a Log Event but no log event found". The situation already had been abnormal: From the wiki, it seems the Kaede Myrellion meeting is only supposed to happen after you've resolved the Kara bar situation, but Kaede showed up immediately after I stepped out of the embassy for the first time. Whatever log event wasn't found was probably tied to that, I'd expect.
Attached is my save file, on the meeting square where Kaede is.
