Short version. DO NOT sell using your characters bazaar on or near a zone boundary (like exit from towns). If you crash you may get perma-bugged bazaar like my character has. Ignore warning if you hear they identified and fixed this.
Support is to report the bug on a form they don't answer (been told to do that three times). It is unknown if or how my character can be fixed. So I want to warn people to avoid selling near zone boundaries for now.
