I go to the my wardrobe and click on avatar. But it never loads, so I can't change my avatar that way. Is there another way to do it?

You'll have to use the beta wardrobe, it'll be shown in the box right above the wardrobe you're probably stuck in an infinite load loop with. You can do everything there except modify your base features as that's currently busted no matter what wardrobe you use.

Thank you! Finally figured it out :D Plus it looks like I don't have to be stuck with that skeleton skin I had before. whoo!

I'm glad you found it! c: Play around with it and have fun, just remember that backgrounds without the HA cutout go under the "Base" layer.
