Hello all. I came online tonight, ran the Gift of the Lotus alert, then went into Atlas's Leverian and listened fully to all of the displays; when I hit escape to leave, I was met with a black screen. When I started hitting keys, I realize I was still getting sound effects as if the Orbiter had loaded, I just couldn't see anything. First screencap below; I only now noticed the chat stuff in the bottom left corner (continued below)
When I hit escape again, the pause menu did come up and was fully functional, including Nightwave. I went into the Options, to Video, and tried to change my Display Mode to see if that would basically reload the graphics. I was on Borderless Fullscreen; I switched to Windowed and hit save. It made the switch but was still just black. Switched back to Borderless Fullscreen and saved, still black. Continued below the screencap.
At this point I exited the game and loaded back in, and it was completely normal.
Hope this helps!
EDIT: I just went into the Grendel Leverian and similarly went through all the displays, but when I exited to the Orbiter this time, it was totally normal. Tried Atlas again (though I admit I didn't bother with the displays) and it didn't happen that time, either. Hopefully this additional information can give you some hints...
