if a mob dies near a sculk cataylyst and there is sculk near by, the sculk spreads.
I guess it has not been a problem and probably will refrain from ever being one. but i am worried. a player might be able to bring eggs and spawn chickens and kill them. to cause the sculk to spread i am not sure how far it would spread.
or the sheep and pigs that spawn in spawn may be breed and killed.
i guess i am not 100% certain how far sculk spreads or if it is an issue. and maybe it has been looked into and not an issue?
