Am I right in thinking that brushes disappear when you select the brush you want to be a trigger then right-click -> trigger -> trigger_buildable in the 2D window?
Correct, Survivor fixed my problem.
Oh, Larva Crap, one problem that I've run into due to my shit memory ( =\ ) does not mean that I am unable to help those with the knowledge I do retain.
Then again, you wouldn't know what help is, would you?
@Survivor - Thanks, I feel like an idiot.

EDIT: Okay, I fixed it, it works now.
When the elevator is triggered once, it won't stop, regardless if there's a reactor or repeater in the proper spot or not..
