Turtle, I need your Admin Super Power to break just a few bedrock blocks, if you would be so kind.
Beacons only work if they have direct view to the sky (or the nether version of that) and since 'sky' is actually bedrock in the Nether, sometimes netherblock gets stuck into the crazy that is the bedrock Nether ceiling. Beacon beam can't go through, yada yada, I need your superpowers.
When we're both on next time I'll show you where exactly. No rush at all.
