Sage naruto use mystery at start, chaining into mei immobilize. Immobilize got reflected onto naruto's clone by ningendo. During naruto's standard attack, he spawned a second clone instead of attacking. Both clones are on the field at once.

This is not the first time funny things happen with reflected immobilize from mei's chase.

That issue still hasn't gotten a response from mods.
