I think pretty much anyone with a mystery that uses a barrier can freeze up the game. But I'm not usre. Any word from the mod?

S327 same problem here, with Sasuke

Hi there,

The Mystery Skills for Sasuke, Gaara, Anko and Haku have all been fixed. During the weekly update,the art for these units' Mystery Skill was updated; a problem with the coding of the source of this new art and the previous one occurred during the process. Please clear your cache and refresh game...

If you still experience this then please let us know... :)
