Woke up to a black sphere clipping through my map...?

I opened my map today to find this: (see three angles of the same phenomenon)

There is no root component, I didn’t put it there, there is just a big black unlit sphere shaped mass that’s obscuring my game…

It seems that any actor placed inside of it also appears black, and some of the nearby particles have gone black too. See below.

My map was working and looking correctly just yesterday. I have not done any work on this map that I am aware of that could be the cause of this…? Does anybody have the slightest idea what this is?

Thanks

Also I should mention that it seems to disappear when I zoom back - see close and far screenshots below:

Found the issue…

It was a rect light on one of my actors which I had edited earlier that day.

I disconnected and reconnected some nodes inside the construction script, and the opaque sphere went away despite the blueprint ultimately being exactly the same lol.

No idea wtf that was about.
