Breachlord doesn't stop his hand slam Attack (with video)

I had my first attempt at the Breachlord just now and died to his hand slam attack, because he didn't stop after just 4 slams (as is normal), but instead continued slamming until I was dead and actually still after I was dead (as you can see in the below video).

Did anyone else have this issue? Couldn't find any threads about it.

I have just encountered the same bug, was dodging hands for a good 30 seconds until killed me, and they kept going after my death as well.

As I'm playing SSF and it takes a good while to collect splinters, this really is killing the will to continue...
