CSS freezing after match

[evanescent_hero]

Hello...I just started using a custom CSS today. The CSS loads fine with no problems. However, sometimes after a match, once I hit Start to get out of the results screen, the game freezes. It's not one of those freezes with that horrendous buzzing sound; the game just won't load or respond to any buttons, including the Home button.

I tried deleting the common5.pac, but the same thing eventually happened. The CSS codes I'm using are below in the spoiler tags. If someone could help me, that'd be greatly appreciated.

Oh. In order, my CSS goes:
First Row: Mario,  Luigi, Peach, Bowser, Lucario, Jigglypuff, Ivysaur, Charizard, Squirtle [they're all independent, with no Trainer], Pikachu
Second Row: Donkey Kong, Diddy Kong, Pit, Wario, Random, Sonic, Snake, Ike, Marth, Yoshi
Third Row: Fox, Falco, Wolf, R.O.B., Olimar, Ice Climbers, Lucas, Ness, Zero Suit Samus, Samus
Fourth Row: Link, Toon Link, Zelda, Sheik, Ganondorf, Mr. Game and Watch, Captain Falcon, King Dedede, Meta Knight, Kirby
There are a total of forty selection spaces, all of them either a character or Random. (None of them are "none.")

Sorry but you are not allowed to view spoiler contents.

Can anyone help me at all?

I was going to say you need Custom Random enable just in case, but you did.
All I can think of is if you replaced some original CSS portraits and one might be screwed up. or you have a value in one of those codes that's making it crash.
50 or 55 slots was the highest it would let you add.

I don't have any CSPs, so it might be an issue with coding. I only have forty slots, so that's not the issue. =/
Thank you for replying.
