that crappy model would happen to be my model. The throwing was already fixed, but I never uploaded it to ESF-world. It's not a skin either, it's a model, I never did the transforming animation either, so it's using the default animation for the evil buu model. The arm I fixed today, but I don't think it's important enough to make people re-dl yet.
Best if you just replace the evilbuu with superbuu, because I used the evilbuu skel for the model.
http://esf-ta.com/superbuu.zip if you want the throwing problem fixed, otherwise, just transform to evilbuu, and the throwing will work perfectly.
*even with the fixed throwing, the dude your throwing won't spin around you so just use it as an evilbuu replacement if the animations bother you that much*
