I was hoping I could get some help with this weird crash. I've hosted many servers before and never had this issue. Now and then the server crashed with "Exception ticking world". Everywhere I looked I rarely found any info on it (usually found ticking entity instead). Any advice I did get (mostly from the modpack owner's discord) was "We don't know and it's near impossible to find out what it is". Here is the crash report: Description: Exception ticking world java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextNode(Unknown Source) at java.util.HashMap$KeyIterator.next(Unknown Source) at net.minecraft.entity.EntityTracker.sendLeashedEntitiesInChunk(EntityTracker.java:386) at net.minecraft.server.management.PlayerChunkMapEntry.sendToPlayers(PlayerChunkMapEntry.java:162) at net.minecraft.server.management.PlayerChunkMap.tick(SourceFile:165) at net.minecraft.world.WorldServer.tick(WorldServer.java:227) at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:756) at net.minecraft.server.dedicated.DedicatedServer.updateTimeLightAndEntities(DedicatedServer.java:397) at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:668) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:526) at java.lang.Thread.run(Unknown Source) If you want the full version, I can link a pastebin if needed. Modpack link: https://www.curseforge.com/minecraft/modpacks/multiblock-madness Some helpful information is that: It seems to only happen when I leave my void world to enter the overworld. Only happens 5-10% of the time. Only happens when leaving the void world, and only the void world. I know it's a slim chance someone could help, but it'd be greatly appreciated. -
thanks a lot bro i knew i shouldve gone on the actual website instead of the discord -

Minecraft Version? Reinstall Java 17 and/or Java 21 If this is still not working, run jarfix https://johann.loefflmann.net/de/software/jarfix/index.html
