Ouch, that sucks. Those temps are way too hot, though! The MMM doesn't thermal until it hits around 220F, but judging by the temps of those cells, I'm thinking that maybe ripple voltage killed the MMM? They must've been really struggling to provide the current required to get that hot, so the first thing that comes into my mind is bad ripple; and Patrick has said before that high voltage ripple from overstressed LiPos can kill an ESC.

Just an idea, but given that there haven't been any other V3 failures...I'm not sure the MMM is at fault here.
