Bug - Normal Resonant Evil Attacking despite being Stunned

[fanghoul]

I just ran into a problem where I was using Doublicious Double, and Resonant Evil Big Band used his Tuba Tuba BB3 on me, and naturally stunned himself in the process. However, after the attack ended, even though he still had a stun counting down on him, he kept attacking me with a combo, rather than going into his stun animation.

Not sure if it's relevant, but because I was using Doublicious, I got stunned at least 3 times by the Tuba Tuba, and I think two of them transferred to Resonant Evil.
