Platform: PS4 Faction: Villain Location: Temple of Source Power, Grail fight Power: Quantum In the final fight against Grail, in the version where she puts the red spiral puddle thing on the ground that pulls you in, if you quantum tunnel out of it you have a chance of crashing the game. Seems to be about a 1 in 4 or so chance in my experience. I've had this occur multiple times. The UI will freeze completely. Trying to bring up a menu, porting to rally, or any other action then freezes the client completely requiring a force kill of the client and restart. It only happens on that specific version of Grail and not on any other version, nor any version of the prior source powered boss.
