Wakapedia posted in chat(and updated the MotD) to let us know about some mission fixes in the game.
We’ve deployed a service-side hotfix onto the LIVE environment that should make “Ship Under Attack” (Resource Drive), Gilly’s Flight School, and Foxwell missions constantly available. Let me know if they start popping back up again!

I’ll try again when I have some time, hopefully it was just a bad night. Didn’t really expect this to be the case considering most of the contracts stayed on the mission list for a while before I tried them. Maybe I was just unlucky at the time.
