If u want to change a quests name in a custom map. you need to go to the trigger editor and find the quest. If u want to be able to change the quest after u have like created it you need to make a trigger with the action that changes the quest there u can change: if it is option/required and name and description and also change the icon^^ hope this is what u wanted
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
