At approximately 10:30pm, eastern time, May 8th, I loaded onto the Scarlet Spear 10 instance before a murex started (but was still able to see it via navigation and it said the next wave had started). I don't recall the exact time, but that's the time around this particular murex wave started.
I got to wave 17 with a random public group and was just shy getting the full amount of credits because the op links broke. It was 39XX scarlet credits/points.
But when we got back to the relay, I didn't have the points in my inventory like as is usually the case and I wasn't on the leader boards. This is despite seeing that the codes I was sending were being received by space teams.
I left the relay and went to a different instance and they still weren't there. I didn't get any completion bonus points either since the instance had completed 70/70 Murex.
I'd post this in the bug reporting thread, but that doesn't seem to be possible to the one that support linked me to, and I can't find one for the PS4.
