Heya, 

Just wondering if any of y'all having the same problem ?

I've tried to Google and it seems to have been a bug in the past.

But yeah.. there is no option for me to exchange my Great Marni stone with wacky Toshi.

Please help 

Thanks :) 

Is this the first Great Marni Stone for that zone that you are exchanging since the update?

If so, have you done the quest with him for the title?  When I was doing the Kagtum one, he only let me exchange after I did the quest.

Yes i have done the quest for the title but stil no option sadly.
