Hey!
I’m doing Prince Ali rescue and Dragon slayer quests at the same time. I’m supposed to talk to Ned about the disguise for Prince Ali, but I asked about Crandor Island before that and now I only get the Dragon slayer dialogue options from him.
You may need to go through every dialogue option with Osman and Leela in order for Ned’s dialogue to appear.
Either that or kill Elvarg before completing Prince Ali
