When I went to Mormar to test other things I came across your change to the staircase mechanics. Much like doors they now respond to a single left click.
Unfortunately, when the command is executed on a down staircase it does not work if there is an up staircase close by. If you are standing on the staircase going up and click the down staircase, you will go up. If you are standing to the north or west of the down staircase and click on the down staircase, you will remain on that level. The only way to go down in mormar is to type a command to move to the staircase, and then type a command to use those stairs.

Additionally, if you click the up staircase too rapidly, you will get stuck in a wall and then get promptly booted to the decayed lands on the mormar climbdown
