What did you expect to happen?

It to

What happened instead?

IT didn't

Why is this bad/What are the consequences?

Broken.

Steps to reproduce the issue.

force a gravity anomaly event via the event panel

Extra information

	if(!drops_core)
		return
	var/turf/T = get_turf(src)
	if(T && length(GLOB.gravity_generators["[T.z]"]))
		var/obj/machinery/gravity_generator/main/G = pick(GLOB.gravity_generators["[T.z]"])
		G.set_broken() //Requires engineering to fix the gravity generator, as it gets overloaded by the anomaly.
		log_and_message_admins("A [name] has detonated a gravity generator")

the issue is the fact that the station gen isn't being seen as a valid option, and im too dumb to figure out why this is the case.
