While I was playing on my factions realm on Friday night, I started expanding my military base and I entered the command as /fill 1395 63 -707 1323 64 -764 air and the results say "Cannot place blocks outside of the world". I keep coming like 50 blocks, 40 blocks, and 25 blocks closer to the first coordinates and there's an error to it. The pictures are sideways now, please consider facing upwards when viewing these.
