Love Knuckle

When I try to use this Flonne attack, the game freezes and I have to reboot. Anyone else have this problem?

I haven't come across that one but there are issues with some animations freezing on the game, that one has been particularly reported along with Laharl's Blazing Knuckle which has crashed the console several times, I've heard Etna's Prinny Raid does the same thing and I've even seen a mothman animation crash it too

Turning off animations doesn't help either, that just makes the console crash as soon as a fire spell is used. I sure hope they fix this issue soon, it's starting to drive me crazy
