I see that there's an issue with un-equiping head items, and people are saying you should equip a different item for that layer. Well.. I want to take the halo off, but I can't figure out what item also uses that layer. x.x

There's a sticky at the top of the forum that deals with this issue.

CAN'T UNEQUIP AN ITEM?? READ HERE!!

It says:

* Astral halo



The Astral halo WAS on the same layer as the headphones, ruby bells etc..but, after moving the cat ears onto that layer I realised that a lot of people would be upset at not being able to equip both ears and halo at the same time.
SO..I tested it out on another layer, and it works ok, apart from the fact the it is now partially obscured by 2 of the male hairstyles, styles 1 and 5..other than that everything seems fine. It is now on the same layer as the Morning/Midnight Dreams bow, so you won't be able to wear that at the same time. but hardly anyone has this item anyway. But, you can now wear the halo with the headphones!

To remove currently equiped Astral Halo

If you have any of these items, and are not currently wearing them, they will unequip the halo, and allow it to move to its new home.

* Yumeh cat ears and tail
* Panda earmuffs
* Bee antennae
* Superstar headphones
* Ruby bells

Ack, thanks. Guess I shoulda looked harder.
