HELP ! Chapter 4 quest ain't working :(

[TGfeu001]

Hello, I made my dragonica server online (chapter 4), everything's running just fine but the main quest (Big Bad Wolf, On the Way) is buggy.. As soon as I clear the big bad world dungeon, no green "Completed" quest appears and I get a 1/1 on this quest but still no complete.. Then it tells me (inside the quest when I look up) to go and talk to a npc in the main city but there I have no one to talk to.. Does anyone knows a thing about it ? Thank you in advance

As far as I know you should do this mission in all difficulties, F1, F2 and F3

Thank you for your message, I'll try to do this again
