Another plague question

[Arkcon]

I think a couple of patches ago, any ship with a medical bay could cure a planet with a plague, even if it wasn't yours. That doesn't seem to work lately -- hey I was just helping out the AI on a mission of mercy. I had noting to do with that plague. Nothing at all. Quit stareing.

I think it still works, but you have to be allies. Maybe it requires a military alliance or better? It might be determined by treaty level.

Wow, I didn't know this either. I set the events to low frequency catastrophic and some games nothing ever happens. So I've only had a plague event a couple times ever.
