Okay I was walking past a bunch of wizards battling Cuthalla in Stormriven when huge white letters saying "Too small!! Try Again!!" popped up on the screen. I ignored it and went down the ramp to collect the portal piece. Once collected I came back near the fight and it went "Too small!! Try again!!" again. Whenever near a Cuthalla fight it pops up with this.
I soon figured its because the wizards in the fight are causing this message to pop up. But outside the battle? This shouldnt be.
Oh, and Cuthalla cheats. be prepared to fight him.
