How to make sure that my planned nether quarry does not cover some other player's portal or builds?
I will fly around ofc, but some portals are inside the solid mass of netherack, e.g. like RX's portal (which I use also).
I could visit all your guys' portals and map them, but what about other machinery?
Ok, lava pumps are usually in the open, no problem. Anything else?
Any suggestions how to avoid the mapping (I am lazy )?
