Mushroom circles grow in circles because they drain the nutrients from the ground, and eventually you have a nutrient barren center that grows with the ring of mushrooms around it.
I wonder if this is something similar, although I’ve not heard of mold using up a resource before.












I finally got round to a significant upgrade to my PC last week. I’ve been running the same PC for 10 years, and it’s really been dying. Fans and HDDs were failing, and it couldn’t play new games at all.
I haven’t replaced my GPU (still on a GTX 980ti) but I jumped to some decent DDR4 RAM, a better CPU, and moved into an SFF case, but I have no confidence any prices are set to stabilise, so I just gave in and built what I could.
