@who

[GM-Ayu]

Problem found: It was someone with a long legitimate party name and a long legitimate guild name. Either one as stand alone is fine, but together it was too long for @who to handle.

The problematic line was "Star Shooting Story" as party name, "Star Force : Reloaded" as guild name. The player in that party and guild only has 5 characters as the name.

Have not found out precisely how many characters is the limit or anything yet though.
