Items Are Freezing My Game

[Smash Warrior™]

I'm not using any common2, 3, 4, or 5 .pacs, no item hacks of any sorts, but when an item spawns, when I throw Link's bombs or Peach's turnips, or when Zero Suit enters the battle and her armor piece fall off, it freezes my games.

So does anyone have an idea on why this is happening suddenly? Also, how can it be fixed?
