I'm assuming the character is supposed to be removed from the main list, so we just need to wait for the list to be updated.

However, when I wrote the dibs counter, there were several peculiarities in the lists including four cases where a shared character was listed in one of the main lists. In at least one of those cases, the user shared the character under the condition that s/he could still keep her in the main list.
Hey if you ever get bored and just think to yourself "man I really just wanna do some scripting right now", you're free to edit the script in a way that does so that if a certain character is mentioned twice in the list, it will make some kind of notice. That way I'll know that it's either a shared character or a mistake of some kind.
