Had this issue, made a post a couple weeks ago.

the response:

but it was being used as support I tried to change it now it does not return

Apparently its being changed as you can see by my picture i used him previously or i wouldn't had leveled him up to 6.

Unsure beyond that, you see in my ss all they had to say about it.

But anyways hope you find out more. good luck friend.

I recall such been mention before.. but oasis says they are not supposed to be release yet as assist nin. ?

thx

you should at least communicate the players so this does not happen again, what are the next ninjas that can happen?? What will be done about it? some still have him on the team, it's not fair not to be able to move

Sometimes I get the message "Different Assist link form of the same Character cannot be simultaneously used." (Eg: For GNW SAI)

even when I did not use two forms of the same ninja. Other times, it just say "Unit is not yet available, blah blah blah~ ~~" XD
