I was just in a T2 Relic run on Telesto, Saturn when another player's Synthesis target appeared. Appeared to be a ballista f sorts. I used the trap and started to scan it but did not have enough time to scan all 4 from the first trap. after that, the last blue target disappeared and all 4 of us had to keep trying to lay traps and scan. eventually another player was able to scan it, but no one knew why it happened in the first place. I was playing as Mirage Prime with Ignis Wraith, Athodai, Lesion, Helios Prime and Deconstructor Prime, all Level 30.
