Any ideas what would cause me to be able to craft my mod's items in single player but not multi? I know this has happened before to other mods I've used, but I forgot what fixed them. I've searched for a while but decided this would be more efficient. Ok fail on my part. I didn't have forge downloaded. Although now I get this Encountered an unexpected exception NoSuchMethodError java.lang.NoSuchMethodError: ModLoader.getMinecraftInstance()Lnet/minecraft/client/Minecraft; at net.minecraftforge.client.MinecraftForgeClient.preloadTexture(MinecraftForgeClient.java:42) at mod_BlockBucks.load(mod_BlockBucks.java:23) at cpw.mods.fml.common.modloader.ModLoaderModContainer.init(ModLoaderModContainer.java:549) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:69) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:317) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:300) at com.google.common.eventbus.EventBus.post(EventBus.java:268) at cpw.mods.fml.common.LoadController.propogateStateMessage(LoadController.java:124) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:69) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:317) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:300) at com.google.common.eventbus.EventBus.post(EventBus.java:268) at cpw.mods.fml.common.LoadController.distributeStateMessage(LoadController.java:81) at cpw.mods.fml.common.Loader.initializeMods(Loader.java:640) at cpw.mods.fml.server.FMLServerHandler.finishServerLoading(FMLServerHandler.java:88) at cpw.mods.fml.common.FMLCommonHandler.onServerStarted(FMLCommonHandler.java:357) at ft.b(DedicatedServer.java:111) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:415) at ep.run(SourceFile:539) [/Code]
