The other day I mentioned to somebody the small pieces of blackrock scattered all over cave floors I see when mining, and they pointed out that blackrock never decays and I could be seeing years’ worth of it piling up. I didn’t know that; I thought everything on the ground disappeared every night to save system resources, although I couldn't imagine who on Legends was mining enough to drop all these pieces every day. So I tested it by putting several pieces of blackrock on the ground in front on my house, and, behold, they stayed put for several days. With blackrock being worth only 10 cleanup points each, I've never felt it worth the trouble to pick it all up and put in the trash can, when I can trash one miasma map for 1,000 points. But I’m wondering if all this blackrock continuing to pile up all over the ground is taxing game resources. Is there some good reason for making blackrock not disappear at night like most everything else left on the ground? Would the game run smoother if the developers made it so blackrock pieces disappeared every night? Should players pick up blackrock pieces to keep the system running smoother? Or is this really not a relevant concern?
