Look through the script. Truce made it so the brick has the ownership of the BLID "1337" and named it Autobridge.
This actually wasn't just for giggles; it accomplished two things. One, it prevents people from building on it and changing its properties, which was a bit inconvinient when you moved and lost all the properties. I didn't want to have to add extra code to preserve the properties, because it wasn't the goal of the mod. Two, if you save a build and people were on Autobridges (admins
can disable them temporarily though), you can clear BL_ID:1337's bricks when you load to get rid of the bridges.
Also, a fact people don't seem to know: Typing /light with something after it will use the light like normal, since Autobridge takes over the command. So you could type /light 1, /light real, or even /light asdfghjkl, and you'd get your light as expected. However, this doesn't always work if there are other mods that utilize the light key (T+T weapons is a popular one), because they didn't expect something to be put after /light.
