Are you in the begining of the game where you first meet Eve? If yes, then click on the upstairs to go up.
If you still encounter bugs, you could try reinstall the game and restart a new save. Or post the picture of the bug you encountered in my DC.
Yes. I tried re installing, and starting new save. The issue is that I can't click the stairs. Eve stays highlighted as if the mouse is on her no matter where the cursor is on the screen. So clicking on the stairs just interacts with Eve again. I will post a pic to the DC later to try to show what I mean. Thanks for a reply.
