Any chance of a quarter of the 'passive mob warp' being turned into a water mob spawn area, to allow fishing and squid hunting etc...
If you need squids and fishing areas, there are islands that offer these things (I offer these :3 ) I know that there aren't many squid farms, but fishing is offered on most islands since all it requires is a few blocks of water...
Agreed with arceus itd be better to build a new area then open that then close warp passive break down an area make the stuff and then rebuild the part they broke support i suppose
