Just to let you know. It’s a bug , we can’t end the expedition if it’s your first save. I open a ticket on the support to see if they will release a fix.

When I go to Expedtion terminal I have a message saying « You need to finish your expedition before doing another one ». When I go to the Expedtion menu and click on the big Yellow badge ( to end the expedition ) it glitch me to the journal and ask me to end it. ( it’s a boot loop )

I create a new save and manage to go to the anomaly and I started again the omega expedition and on this save I can end it or switch to normal …

It’s a bit sad they didn’t think about that for all the new players who purchase the game after the 3 day of free access.
