Hi, can anyone help with an issue I am having. So I completed the the whisper heroic to unlock the whisper catalyst and went back to collect all 5 chests. I opened all 5 chests, but when I use the vex gate, only 6 oracles appear instead of 7. Oracle 5 does not appear and I am unable to complete the sequence. Is this a bug in the game, or am I doing something wrong?
