Kole lagged.

I was in Cruel difficulty (hardcore) and was facing Kole, but there was clearly some sort of connection issue/server bug where I was 2 rooms away, reappeared in front of Kole in the blink of an eye (wasn't his hook) and got 1-shotted by his ground slam the moment after. To be honest this is really unfair.. Like how am I supposed to avoid this from happening? There was nothing I could do and I died to a technical error.
