Strange Bug

Always that I begin to lay the module, I spawn with this weird hood with some sunglasses.

Hello, this is strange, the hood is a "tail", (i.e. as a nwn model) so your character has probably been modified by a script (maybe a DM has used a special wand to add this to you)
Just ask for a DM to remove this by using a dm wand.

That solved it, thanks.
