I fixed a couple text errors in the game today. One of which would qualify as a genuine bug. After certain major quest lines are completed, a pop up panel appears with a short synopsis of what happened. That panel had a text that said "Press enter to continue."
However the enter key was no longer being used, and it was instead changed to the "Y" or approval key.
So the new version should sow "press 'Y' to continue" or whatever key you may have assigned as the approval key.
