Level up scavage missions

Why are my missions gone for level up? I have two 100k and a 60k. I had everything unlocked. They don’t even show up on Cool down. I run missions all the time and end up having everything on Cool down for a few days. But never get my level up ones. It makes level ups impossible. Very frustrating.

most not to say all send the mission days before and open them in the event … have you tried that? … It is quite simple and certainly do not cancel missions if it is running

They don’t even show up any more

Not sure. I was having them pop up before previous lvl up but when the lvl up starts. The do missions disappear. Coincidence?!
