After this next reset (assuming we don't have a water world as Marko said ) I am putting a compact, resource friendly Iron farm at the wilds hub to supplement iron production for the rails and other server builds.
To that end in a bid to organise myself I am putting a chest near the wilds portal on the main map with the stuff I need to build it.
The farm itself is quick and easy to build, however yesterday it took me something stupid like 8 hours to get the villagers I needed into both levels to get it running, so any assistance with populating it once it's done would be appreciated.
The farm produces ~50 ingots an hour, doesn't seem like much but thats more than 2 stacks of iron blocks a day and it will run 24/7 (as long as there is someone in the wilds)
