What title says. They do not appear ever. Period.

It's been broken since at least yesterday. I put in a ticket for that last night.

Hey, wow! no station guards? why tf do I not log on at the interesting times?

Bug, or "pirate station"? Super excited either way!

We'll look into it, thanks for the ticket.

Could it be someone luring the guards way out of clipping range

No, they're just not present.
