Hi Noren

To answer your question, it is after.
My experiences are from when chaos turns invulnerable, and you then dps down the crystals. Could happen with any number of crystals still remaining, often on average when 3 crystals remain, but it really sucks when you're on the last crystal and it crashes... Doh!
I can't currently do any testing sorry, as my main PC is out of action while waiting on a replacement MB.
