I've got a couple of World Mines that I've manually set to minimum priority, and not quite enough workers to go around- so this batch represents those mines... which are sitting completely idle anyways, since I'm using pause states to remind my future self of which ones are depleted and which ones aren't (maybe depleted World Mines should disappear or fade, but I think I've already seen a suggestion like that). However, when I click on that badge... nothing happens. Were it a structure on the island, it would fast-pan to it- but it can't do that with World Mines, and it gives me no indication that the issue is on a World Mine.
Can it? Indicate that the issue is a World Mine, that is, and maybe even tell me which ones? I don't think it'd be a good idea to kick open the World Map, just a tooltip.
Or a separate "World Mine has Not Enough Workers" badge so it doesn't get conflated/confused with island structures.
