When I sent my dragons on quests, they didn't return and I can't do that quest anymore

@Khoi-Chung Send a detailed report to support. You will need to explain a bit more. What dragons were they, what quests did you send them on, can you still see the quest as incomplete, how long ago? They will need more than what you posted here

You can reach support through your ingame link. Instructions are below in my signature line.

Sometimes dragons stuck on tower quests. You can only free them on PC or Puffin browser. Choose them for breeding or training. That should free them.
