Removed two missions that gave credits as completion bonus and left one mission that gave cycles as completion bonus.
Did this multiple hours ago and the timer said around 1h wait till new missions when i logged off.
Logged back in couple hours later and still said 1h till new missions and my two free mission slots were left empty.
Yes i am certain it’s been over 1 hour since i removed my old credit missions.
Clock seemed to not have moved at all. My guess is that the mission renewal skipped filling credit missions because the events cycle mission did some herp derp to the system. And i happened to log back in to see the very similar 1h left mark for a missions.
