Just had a breakthrough... there seem to be name/icon issues that are tied specifically to the No Fire Zone event, as well as scripts setting any of a half-dozen net-synced jjPLAYER properties, including jjPLAYER::noFire. That must be why we were having no luck reproducing it outside of the Street Fight levels from Clank's playlog. Right now it seems more obviously tied to missing skulls than red names, but I can imagine them being the same cause.
