After being forcegreeted by Athando Andas (TR_m4_Athando_Andas), the "Certificate of Credibility" topic does not show up with any merchants or guards in Andothren (Unless it's supposed to be for one specific merchant or guard that I missed, but in that case it should probably be changed to all of them.) This makes it impossible to complete "Certificate of Credibility" (TR_m4_And_Credibility) by realizing that it's a scam, and you have to either fall for it or deliberately avoid his forcegreet every time you go past in order to get the quest out of your journal.
