Cant complete quests

[ljibarra]

Once some quests are completed and you try to hand them in and click complete, nothing happens.
So stuck on the same quest and cant continue.

Hello !
You can use the admin commands (when it's not fixed so you can go on)
FIRST you need an addon to know the ID of your quest like : ShowQuestID
https://www.curseforge.com/wow/addons/showquestid

Then you open your quest, note the ID on the upper right corner and use the commands :
.quest complete ID
Ends the quest

.quest reward ID
If the first one didn't worked

Maybe there are other ideas but that's the only one I found yet
