1. Yaeger's charm flag is only currently set at the stage prior to the CotW quest; I'm not sure why that is the case if you handed in the four quest items to Lilly successfuly. This means Yaeger would need to do the quest in the CotW again. However, as you've had quite a bit of trouble with this,
I set it to the right flag value now so Yaeger can simply hand in the seventh charm now. If it doesn't work, please let me know. PS you can do this now, no need to wait for a reboot - character flags change when zoning/logging in.
2. Figgle: I'm sorry, there was a typo in the quest file for Figgle and he wasn't actually designed to accept quest flags, so I changed that too. It should be fixed now, he works fine on the test server. It'll be fixed on live pending a reboot (please try again after the next reboot - I'll see if we can do one earlier than the normally scheduled reboot next week).
I also just tested Lilly on test and she works as expected.
If you've completed the sixth charm quest (group instance) but not yet completed the 7th (Riwwi), she replies with her generic greeting and won't accept items.
If you've not yet completed the sixth charm, Figgle will now say his generic text about ancient creatures but nothing else.
If you've completed the sixth charm, Figgle will discuss the Riwwi games and allow you to start the quest.
If you've completed the Riwwi games and have the seventh charm, Lilly will speak to you about the 8th charm quest.
I just tested all scenarios on test and it seems good now. While I was at it, I corrected some grammar and spelling in Figgle's script

Sorry for the inconvenience you've suffered with this and thanks for your patience.
