If you stumbled upon some pages that were complaining about exceptions, I am terribly sorry about that.
Some forum threads and profile pages with comments were breaking due to some issues with the new bbcode parser.
The issue has been fixed. If you for some reason get served pages that are completely broken, please PM me. I am working on a solution right now that will notify automatically if something like this comes up again.
Thanks to the moderator team for bringing this to my attention.
