This char: https://eq.magelo.com/profile/2614988 was given a minor update to the charm slot and when Magelo sync was run, it detected the correct zone, but the char failed to update or appear by name.
EDIT: I had also updated another char a few minutes before with no problems.
Weird this happened...
I will mark the issue has fixed but dont hesitate to get back to me if it happens again.
And if it does, it would be useful to paste your Magelo Sync log.
