Side missions and nerf

If I go on Galaxy to another map I see the side missions (yellow callsign)
After travelling to this map they disappear but if search and find them they are there
Whats wrong ?

Was Fl4K nerfed again ? Sunday I could easily beat Capt Traut within 15 seconds .
Yesterday I did no Damage at all (same build same weapon)

I think something glitched out last night. I had a run on KataZer0 where nothing phased him for like 45 seconds. Interestingly enough. My friend and I both recorded that because we were trying to show off my Instagank. But it was probably the same fluke for you
