Obsidian is now breakable via creeper eggs. Of course, creeper eggs will not break anything if submerged in water. 3 hits are required to break obsidian, whether that be through creeper eggs or tnt. You can check the durability of obsidian by left clicking the block with a potato.
Factions Warps have been added. Each Faction can have a maximum of 3 and they can be password protected if you wish. Each warp costs $100 to create. Warps can be created using the command /f createwarp.
P.S. Happy 2017!
