My server has crashed twice with this exception:

java.util.ConcurrentModificationException
at java.util.HashMap$HashIterator.remove(HashMap.java:1459)
at net.minecraft.world.gen.ChunkProviderServer.tick(ChunkProviderServer.java:262)
at net.minecraft.world.WorldServer.tick(WorldServer.java:207)

at java.lang.Thread.run(Thread.java:748)

 

I realize this bug is not actionable at this point. I'm filing it in case other people also hit it and can narrow it down.

 

My server is running Manufactio version 0.93 with these added mods:

  • forge-1.12.2-14.23.5.2822-universal.jar
  • Tiquality-FAT-1.12.2-GAMMA-1.0.1.jar
  • FTBLib-5.4.1.95.jar
  • FTBUtilities-5.4.0.92.jar
  • DiscordIntegration-mc1.12.2-3.0.5.jar
  • Chunk Pregenerator V1.12-2.1.jar
  • spark-forge.jar (build #42)

The players said it crashed while someone was claiming a chunk with FTB. Although other players have already claimed chunks. So I'm not sure if that's the trigger.
