Steps:
Before the update I accepted Trial 648 Spawn and Kill Ankabut Four times in North Gustaberg (S) with the Radennotachi equipped.
After killing Ankabut 4x and receiving the quest updated telling me to go back to the magian moogle, I try trading him the Radennotachi to continue with the trials, but this is the text I keep getting:
Magian Moogle: You have done well, kupo.
Magian Moogle: You must dispose of the radennotachi in your possession before I can confer upon you another one.
The magian moogle resturns your radennotachi.
Even when I recheck the quest with the magian moogle, it says that I have killed the Ankabut the 4 times. Still I am unable to move forward.

Check your inventory, all wardrobes and lockers, etc....

Do you have another Radennotachi in your possession too? That will trigger what you received as shown.

Using /itemsearch "Radennotachi" will answer that quickly enough.

They broke it, they already fixed it. You're twelve hours late.
