I have Errors when Either Generating Ore that is Too large (like a vein of 64) and generating a Biome, they both give the same basic error, I'm trying to figure out what is wrong with the Biome Error at the moment, and the Crash report is this: [embed=425,349]2013-08-30 19:46:18 [iNFO] [sTDERR] java.lang.NullPointerException 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.World.getTopSolidOrLiquidBlock(World.java:2004) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.biome.BiomeDecorator.decorate(BiomeDecorator.java:219) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.biome.BiomeDecorator.decorate(BiomeDecorator.java:196) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.biome.BiomeGenBase.decorate(BiomeGenBase.java:366) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.gen.ChunkProviderGenerate.populate(ChunkProviderGenerate.java:573) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.gen.ChunkProviderServer.populate(ChunkProviderServer.java:258) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.chunk.Chunk.populateChunk(Chunk.java:1249) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.world.gen.ChunkProviderServer.loadChunk(ChunkProviderServer.java:153) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.initialWorldChunkLoad(MinecraftServer.java:292) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.server.integrated.IntegratedServer.loadAllWorlds(IntegratedServer.java:90) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.server.integrated.IntegratedServer.startServer(IntegratedServer.java:107) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:443) 2013-08-30 19:46:18 [iNFO] [sTDERR] at net.minecraft.server.ThreadMinecraftServer.run(ThreadMinecraftServer.java:16) 2013-08-30 19:46:18 [sEVERE] [Minecraft-Server] Encountered an unexpected exception NullPointerException java.lang.NullPointerException at net.minecraft.world.World.getTopSolidOrLiquidBlock(World.java:2004) at net.minecraft.world.biome.BiomeDecorator.decorate(BiomeDecorator.java:219) at net.minecraft.world.biome.BiomeDecorator.decorate(BiomeDecorator.java:196) at net.minecraft.world.biome.BiomeGenBase.decorate(BiomeGenBase.java:366) at net.minecraft.world.gen.ChunkProviderGenerate.populate(ChunkProviderGenerate.java:573) at net.minecraft.world.gen.ChunkProviderServer.populate(ChunkProviderServer.java:258) at net.minecraft.world.chunk.Chunk.populateChunk(Chunk.java:1249) at net.minecraft.world.gen.ChunkProviderServer.loadChunk(ChunkProviderServer.java:153) at net.minecraft.server.MinecraftServer.initialWorldChunkLoad(MinecraftServer.java:292) at net.minecraft.server.integrated.IntegratedServer.loadAllWorlds(IntegratedServer.java:90) at net.minecraft.server.integrated.IntegratedServer.startServer(IntegratedServer.java:107) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:443) at net.minecraft.server.ThreadMinecraftServer.run(ThreadMinecraftServer.java:16) 2013-08-30 19:46:18 [sEVERE] [Minecraft-Server] This crash report has been saved to: C:\Users\Max Decay\Desktop\Everything\MineCraft\Mods\forge\mcp\jars\.\crash-reports\crash-2013-08-30_19.46.18-server.txt 2013-08-30 19:46:18 [iNFO] [Minecraft-Server] Stopping server 2013-08-30 19:46:18 [iNFO] [Minecraft-Server] Saving players 2013-08-30 19:46:18 [iNFO] [Minecraft-Server] Saving worlds 2013-08-30 19:46:18 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/Overworld 2013-08-30 19:46:18 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/Nether 2013-08-30 19:46:18 [iNFO] [Minecraft-Server] Saving chunks for level 'New World'/The End 2013-08-30 19:46:18 [iNFO] [ForgeModLoader] Unloading dimension 0 2013-08-30 19:46:18 [iNFO] [ForgeModLoader] Unloading dimension -1 2013-08-30 19:46:18 [iNFO] [ForgeModLoader] Unloading dimension 1 2013-08-30 19:46:18 [iNFO] [ForgeModLoader] The state engine was in incorrect state SERVER_STARTING and forced into state SERVER_STOPPED.
