    Hello, I had a character join my server which generated this log entry:

    (dudes.ip.address.ok) from 'guest' group joined. (11/20)

    The start of that line *is* their character name, it's just whitespace characters or something. Showed up in the logs as 'NUL NUL'

    I believe that when this happened it nuked my superadmins ability to send commands to tshock. Command line commands were ignored as well as in game ones, and we had to kill the service.

    Is this a vulnerability of tshock? Is there some way to work around it? (Besides aggressive white-listing)?

    Any help would be appreciated.
