Networking Cart - Problem?

[AbbadonOfHell]

When I played 8 months or so ago a networking cart could be used to open a door by setting it to the proper frequency and bumping the door to get a "door locked" message along with the doors I.P. which you used to open it with the cart. It now seems that you only get the messages when a door actually opens, is this supposed be a feature now or is it a bug?
