I've completed the Orchel trading quest, the racism quest, and Kayelinth's event at Rakake, but when I talk to Filauria Lyrandis and Keylessa in Orchel's town hall I don't get any new scenes or events. Is there something else that must be done to trigger their scenes/events.
Not really. Have you probably updated? The new version number should show in the title screen.
If it's a problem with your files, consider downloading the full version again and copy the entire content of your save folder to the new download.
Else, if you're on windows, can you post your save file? Then I could check if something didn't properly trigger for you.
