Hello everyone. I use TC v.2.1.7. and CraftBukkit-1.2.4-R0.1-MCPC.jar (SNAPSHOT-61 - https://github.com/MinecraftPortCentral/CraftBukkit/downloads - CraftBukkit + ModLoaderMP + Forge), i also tested my configs with old versions of TerrainControl and latest MCPC Builds. My mod: http://www.mediafire.com/?49281559dng0id5 , it simply adds new blocks without their generation in the world. Their IDs: 230-236 and 237. I have identified block with ID 237, because it was normally added. After I added blocks with IDs 230-236, the server become returned this error: http://pastebin.com/9uf3Bm03 (Full server logs: http://pastebin.com/7Zq8LFWq ).
