I am fairly new to the game and I have been running planetary scan missions for a while now to gain faction rep and decent money but I noticed some weirdness.
Sometimes a scan mission for another planet will complete when I scan a data link . On one occasion I have managed to complete an entire stack of scan missions trying to get the one listed for the planet I'm on.
The markers for where to scan do not always clear when the mission is completed.
And occasionally while doing these missions my Nav Screen freezes and I am unable to select anything on the screen.
Not sure if it's my game or if it's an issue with scans in general.
The freezing is probably a ps4 thing
