For those of you that own the downloadable version or have experienced this:

Today I was fooling around with the arena and it froze. I had set up four Triton Soldiers with infinite health and was using the Horn of Boreas to see how big of a combo I could get.

I tried it again about 30 minutes ago and the same thing happened. On top of it, the game got corrupted so I have to re-download it. -_-

Is it just my game/PSP, or has anyone else experienced anything similar to this?
