I created a single player Minecraft 1.7.2 world and moved it over the lastest version of Spigot (one for minecraft 1.7). Its seems this version is not the same as the release version of minecraft because a lot of the trees visible in the single player game are not visible in the spigot server. Huge forests disappear and are replace with just dirt squares where trees should be. Knowing this ahead of time would have been good. I spent many hours looking for biomes which all of a sudden disappeared. When will the full spigot version be released so the Server matches the single player maps? To reproduce the problem use the release version of Minecraft to create a large biome map using this seed: -32234290. You will spawn by a large forest filled with large oak trees. The new 2x2 block ones. Copy the world folder over to your new Spigot folder and start the server. Use Minecraft 1.7.2 to enter the server. Note: All those trees will now be gone. On the ground is only a 2x2 dirt patch.
