      My server has some chunks that will crash the server when they load. This seems to be due to an entity that is outside of the region with a very high Y-value.

       

      java.lang.IllegalStateException: Entity EntityWitherSkull['Wither Skull'/811, l='ServerLevel[world]', x=-4464.26, y=2560.84, z=-2255.58] is not in the region	at com.google.common.base.Preconditions.checkState(Preconditions.java:590) ~[guava-31.0.1-jre.jar:?]	at org.bukkit.craftbukkit.v1_18_R1.generator.CraftLimitedRegion.saveEntities(CraftLimitedRegion.java:98) ~[spigot-1.18.1-R0.1-SNAPSHOT.jar:3408-Spigot-f4ff00f-74a5cc8]

       

      I can not reproduce this problem from scratch, this server is very old so it's possible that this entity has been there since prior versions of MC/Spigot that did not have this check?

      I also can't identify the faulty region files, but if you do need a repro case and can help me map those x/z coordinates to a region file, I'm happy to attach it!

      It seems odd I have never seen this before, but since updating to 1.18 my server crashes every few days, when certain players try to log in and these broken chunks load. I looked through git history and the check doesn't seem that new, so I'm confused as to what's going on- something to do with the world height change, I'm guessing?

      The check it's hitting specifically is from CraftLimitedRegion, here:

       

      if (entity.isAlive()) {
    // check if entity is still in region or if it got teleported outside it
    Preconditions.checkState(region.contains(entity.getX(), entity.getY(), entity.getZ()), "Entity %s is not in the region", entity);
    access.addFreshEntity(entity);
}

       

      Would it be possible to skip saving the entity in this case, rather than hard-crashing the server?

      Full stack trace - most of this will repeat several times before the server shuts down.

      I can attach the full logs if needed, I would have to sanitize IPs and such.

      I am not the only one having this issue, but it must be rare as I can't find anything here or via Google.

      Thank you for any help you can give!
