CSS when I'm about to select player 4's character?

[Kyouma]

As the title says, I've been messing with my build lately and I noticed I can use 3 simultaneous players but when I try to use  4th one, the game crashes when I move the cursor near to any character...
Anybody knows what causes it? Could it be any setting with brawlex or something inside the sc_selchar?

Think it could have something to do with the CSS expansion version? The unstable version lags horrendously on three players.

It's an edit of Nebulon's build's last version, I don't really know if he's using said vrsion but I don't think so because the unedited version works fine

If you can't figure it out I can see if Dolphin debug has anything to say about your SD card contents.
