Bedrock Gap Insurance + Flat Earth v2.0 Old favorite from hMod returns! This is a must-have for servers running worlds from very old verions of Minecraft (pre-Halloween 2010 update), and a best seller for server admins who love a smooth bottom. (that's what she said) This is a very simple plugin that exists to help with world consistency and has two features - Bedrock Gap Insurance and Flat Earth. Bedrock Gap Insurance automagically replaces every non-bedrock block at the very bottom of the world with bedrock. This will eliminate "gaps" in the world in which players can fall through. This feature is primarily useful for servers running on very old world versions, specifically before this was fixed in the game core around the Halloween 2010 update. Maps that has been newly generated since then can safely leave this feature disabled. Flat Earth automagically converts all non-bottom layers of bedrock into smooth stone. This will effectively make the upper 4 layers of bedrock now breakable, giving you an extra 4 layers in your world to build in. Note that this ONLY affects the 4 layers above the bottom layer; anything that may be built with bedrock that is not in this area will be unaffected. For both features, the plugin checks all of the 0th to 4th level blocks in world chunks as they are loaded by the server. This is a huge performance improvement over the old version for hMod, which checked a small area around every player as they moved around Major thanks to flames for helping with the porting from hMod to Bukkit!
