Illum Chests & Secrets

I've had a similar problem with 3 sense echos. They are: On Bogano #2 of The Creature and #13 of The Researcher, and on Zeffo #2 from the Venator Wreck. These are not difficlut to find, their out in the open. I've finished the game with 100% on every planet. When I look at videos I see where others have found them, but they do not show up when I get to those places. I recall a couple things that may have been glitches when I was opening chests or sense echos but I cannot be certain that it was at those 3 spots. I may have pressed a button too soon and exited out before the game was finished giving me credit. What I experienced seemed odd at the time but I didn't look to verify that I had been given credit for my find. 

I restarted a new game and already got sense echo #13 "Faded Mural"  on Bogano with no problem. I don't get it Big Dan! In my second go through I will be sure to check every chest, secrete and sense echo to assure that I got credit for it.
