Area Trigger Not Working? Did A Change Happen?

[kiddan]

Title says a bit, I'm trying to use area triggers on a station but you cannot seem to connect them to anything (except area detectors.) They don't seem to change to another state when walked through either, so I am either really nooby about some change that happened, or this might be a bug.

Note: I have made these work before, I dunno why things seem to have changed.

Edit: Another note: You interact with the R key on Area Triggers either

Place them next to an activation modules, that's how they have always worked.
