Also add the latest.log from /logs/

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

Hallo liebes Forge team, mein forge installer nimmt nicht die Java datei an bzw. zeigt nicht das Symbol und öffnet immer nur kurz die console und schließt sich dann wieder.  Ich habe die neueste java datei und die neueste forge datei und es öffnet trotzdem nichts.  Könntet ihr mir dabei weiterhelfen?
