To put it simply, I've had a few times over recent days where after finishing a run, the game would not load Haven. Today it was a black screen.

Yesterday, I remember that the acquired heat window was still there.

Both times (certainly today, not 100% sure about yesterday) I had just run the prestige mission (not danger) and it was my first run of the day. The cursor still worked, but of course, nothing I could use it on :P.
