We accidentally deleted the Vex Transponder after completing the step to kill 100 Vex. Now we can't progress on the Black Armory. We tried going to Ada and checking through all her tabs but no luck. Also checked Failsafe on Nessus. Any ideas on where we need to go to pick up the transponder again? We've killed many, many Vex all over Destiny since we deleted and it doesn't appear to be dropping again. Thanks in advance for all your help!
