That's odd, I tried 'em all in game and got no freezes.

Which ones are you using? And are you sure it's not the names? Remember you have to decrease the info.pac's size for it not to freezes by deleting part of the texts.
Glad to know you're enjoying it. ^^

I didn't know that, however I compressed them using cmpr instead of CI8 and it works now.

The portraits seem to be freezing my game...

Awesome PSA aside from that.
