Subject: [PATCH] Protect Bedrock and End Portal/Frames from being destroyed
|
|
|
|
This fixes exploits that let players destroy bedrock by Pistons, explosions
|
|
and Mushrooom/Tree generation.
|
|
|
|
These blocks are designed to not be broken except by creative players/commands.
|
|
So protect them from a multitude of methods of destroying them.
|
|
|
|
A config is provided if you rather let players use these exploits, and let
|
|
them destroy the worlds End Portals and get on top of the nether easy.
