I am a bit....impatient waiting and waiting time again for a defend the warsat challenge to appear on mars. I require to complete a final Defend the Warsat on mars for a quest involving the Ikelos Fusion Core. Time and time again I arrive on mars and wait for only Eliminate The Target challenges to appear. The one time a Defend the Warsat appeared, it did not show. Just the objective, and it disappeared. I really need help with this one. I have drove everywhere on mars, and to no avail. Is there a bug with Mars that I am not familiar with, or is there just a problem with Destiny I was not warned about?
