Bedrock glitch and island regen.

[AmazedMender16]

Description

Describe the bug

When we remove the Bedrock at our island followed by a tp away and /back, the Bedrock block and its surrounding gets a reset (regen). Users are able to take away the bedrock by using minecraft glitches. Please see: https://youtu.be/32t3gIXP3uc

Steps to reproduce the behavior

1) Create an island 2) Remove bedrock by doing the glitch. 3) Go to another world and return.

This affects nether and end islands but not over world. It's a safety mechanism to make sure these islands exist if for example, the nether world or end world get deleted. The check is done on whether there is AIR at the island central location.

@AmazedMender16 Can you give details on the glitch process because I want to test countermeasures. You can Discord me the details.

[tastybento]

I wonder if the bedrock removal glitch is still working on 1.15?

[BONNe]

If not the existing, then someone will always find a new one :D Bedrock removal is basic for a lot of technical players so they always will find a way :)

[tastybento]

Right. I'm going to make this autopasting an option.

[tastybento]

You'll need an updated BSKyBlock addon to see the config option in config.yml. I'll add that now.

The config setting is defaulted on to retain backwards compatibility, but the new BSkyBlock/AcidIsland addons have it defaulted off.
