I've run into an issue several times now. Occasionally a newly added character or even a character that has been in my guild and on my site for months, will basically disappear.
They don't show up as "claimed" by the member. I can't assign (claim) them directly to another member. I might be able to claim them with my account, but they don't show up in my list of characters in most parts of the site, and if I unclaim them, they don't show up in the list of claimable characters that I can assign to another member.
They don't get tracked in EQI imports of my raid dumps. They are clearly in the text file, but it doesn't automatically add them to the event in Rapid Raid like it does the rest of the characters in the file. They can be added manually to the event after the fact, because they do show up in the list of available members.
They don't show up in the raid roster under their class, even if you check the box next to their name in the list of eligible characters and add them to the Active role.
They are marked as raid eligible, but they don't show up in the list where you can edit their eligible date.
I really don't want to delete this character and manually add them back to every event like I've had to do in the past.
