Like I said, I was standing at the left side at the middle left oracle (maybe 2-3 meters right of it). Equiped weapon was a full upgraded Vision of Clonfluence. I was playing my new titan and got his first raid piece at the oracle checkpoint (but I didn't equip it). I gave a lot of attention, but I did not notice anything else strange. Gonna do a few more raids today and will try to reproduce this. I keep you updated.
