Sora freezes Sub-Space Emissary

[xZedkiel]

So I'm playing through the SSE and I kill myself to show my friend Sora.. and it freezes. I remember having the same problem before when I played with Sora and Ven on SSE (the part where you and 2P are both Pit) and even that freezes. Why is that? I'm playing with Riivo and have the Fire Master Alixander PSA on, it used to freeze without Alixander too :(.

Sometimes he freezes up in a regular match too.
