Cube Expansion through Quest

I noticed that the "A Lucky Day" quest is now working as my Ranger triggered it and got the expansion today. My question is that I have a Templar that has completed the quest about a month ago when it was not working. I cannot find a way to get the expansion slot from this quest. Are there any options for my Templar to get this expansion slot? I did use the search feature and the posts were older than the fix update.

 

i have the same situation with my characters aswell. dont think they can reset the quest though .
