If you do this in the original it doesn't crash, but it does break the puzzle. It makes the starmap be all black and you can't progress further.

PR995 solves this.

The logic in CStarCrosshairs::selectStar was allowing previously marked/locked stars to be deselected via the skymap. Now the code checks that that the new star selection is not already in the queue (_entries) unless it is the most recent one then that one can be removed since its not locked.

It previously crashed if

  1. You had 2 stars locked on and you tried to remove the 1st
  2. Had 1 locked and 1 unlocked and you tried to unlock the 1st
  3. Had 2 locked and 1 unlocked and you tried to unlock any of the other two locked stars.
