jinlar, that's most likely not a bug. That's most likely your player setting the character to "Public: No." While editing a character, you'll note a field which says "Public?" with a check box next to it. If the check box is not checked, only the author of the character will be able to view it. See if you can talk you player into editing his character, checking that box, and saving. That should, hopefully, solve the problem.

campaign - The Sigils of Meshtun
I have two other players whose characters loaded fine and are linked in the "Players" box.
A third player, tomtomettom, just linked his new PC, but when I click on the link I'm shunted to a "You are not authorized" page on the site.
