Hey guys! I need your help! Yesterday everything with mt minecraft server was ok, and i was playing with friends, but then, today's morning it happened. I do not have any backups of my map, that is why I wanted your help, if there is any possibility to fix this. The problem is, when i launch Tekkit Lite server it replies to me with an error: [sEVERE] Encountered an unexpected exception ConcurrentModificationException java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(Unknown Source) at java.util.HashMap$KeyIterator.next(Unknown Source) at immibis.chunkloader.DimensionalAnchors.loadForcedWorlds(DimensionalAnchors.java:189) 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 cpw.mods.fml.common.FMLModContainer.handleModStateEvent(FMLModContainer.java:485) at sun.reflect.GeneratedMethodAccessor2.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:140) 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:83) at cpw.mods.fml.common.Loader.serverStarting(Loader.java:700) at cpw.mods.fml.common.FMLCommonHandler.handleServerStarting(FMLCommonHandler.java:309) at ho.c(DedicatedServer.java:198) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:458) at fy.run(SourceFile:849) I do not know how to fix this, but if anyone could help, i will really apprectiate it.
