Description: Exception in server tick loop

java.util.concurrent.CompletionException: com.ishland.c2me.fixes.worldgen.threading_issues.common.CheckedThreadLocalRandom$1: ThreadLocalRandom accessed from a different thread (owner: Server thread, current: C2ME worker #1)
This is usually NOT a bug in C2ME, but a bug in another mod or in vanilla code.
Possible solutions:

  • Find possible causes in the stack trace below and
    • if caused by another mod, report this to the corresponding mod authors
    • if no other mods are involved, report this to C2ME

(You may make this a fatal warning instead of a hard crash with fixes.enforceSafeWorldRandomAccess setting in c2me.toml)

@peak kettle As much as it is not an C2ME bug, the crash is because of C2ME

#

C2me to protect data will force a crash when threads are not acting as intended.

#

Multiple people have had the same issue. Its due to the ghosts mod doing random number generating that doesnt follow the protection standards of C2ME, so it just crashes it thinking the data is corrupting.

#

You can stop C2ME from crashing by editing the toml file.

Find c2me.toml in the config
Set fixes.enforceSafeWorldRandomAccess = false
