How do I can go on to next quest??

[Jiyi]

I sent all the characters to Edgeborough Lane except Buck and my progress rate is 90.

After I finish Burke's quest called "The Vision of Oil," Burke doesn't give me any quests.
What should I do??

Even after a few days, he doesn't give me a quest.

Keep visiting different islands?

If you're only at 90%, that suggests you've missed something (or someone)

Have you done Daria and Jackie?

Oh I missed Daria! Thx!
