I was originally trying to get a rather complex entity setup working, one which required a multisource to work. However, it would appear I'm incapable of getting even the simplest multisource setup to function. I tried to break it down to the simplest level, one even highlighted in our multisource tutorial: unlocking a door with three buttons. However, absolutely none of it works. I went so far as to copy the same setup from the example map, but it refuses to work at all when I do it.
Here's my exact setup. This is all I did to the entities, everything else is the default: I have three buttons. These buttons target a multisource, and stay on indefinitely. The door's master is set to the name of the multisource.
That's it, it's the same way I see it in the example map, and that's how they say to do it in the tutorial. Nothing's changed that I can see, but for me nothing happens. My door is unlocked when I compile the map, and the buttons do absolutely nothing.
