[MC-36990] Mobs not spawning above LC 79

Due to the changes made earlier in I believe... 13w38a. There were changes on how mobs would spawn in chunks and this causes problems with them spawning above 79. I don't know if this issues has been reported already and or is planned to be fixed or is for a future feature, I just thought it might have been a bug in the mob spawning.

Natural mob-spawns ( above LC 79 ( To my knowledge )

NOT affected;
Mob Spawner's

Cannot confirm.

Please do not mark issues as private, unless your bug report is an exploit or contains information about your username or server.

Would you like me to take some screenshots of this?

Callum Morris 2013-10-24T19:01:06Z

Proof of mobs not spawning in a nether fortress. I can give more evidence if needed.

Talven81 2013-10-24T19:03:51Z

Does this occur in the overworld?

Callum Morris 2013-10-24T19:05:12Z

More of a mobs spawner spawning at 127 Lc but no natural.

Yes. I will post some proof now. Let me generate a new world real quick.

Callum Morris 2013-10-24T19:10:28Z

Here is the Overworld proof with a new world left to generate.

Talven81 2013-10-24T19:10:55Z

Still cannot confirm, see screenshot.

Callum Morris 2013-10-24T19:12:08Z

I see.

Let me try in a flat lands.

Callum Morris 2013-10-24T19:14:31Z

Hmm. Seems to be working in the Over-world. Same problem in the nether tough.

Sorry for giving you false information about the Over-world.

Nether is also spawning correctly for me.

Please attach the complete output of the "Development console" tab of the launcher.

Server-side AND Client?

Callum Morris 2013-10-24T19:30:12Z

I have white-listed you on the server if you would like to see the problem in action.

I set your dev console output to moderators only since it contained information regarding your server. The mods can still see it.

Callum Morris 2013-10-24T20:04:23Z

Thank you. If you need to join the server to see the conditions of mobs not spawning, tell me.

I have the same problem on my private server. In a single player offline world mobs seem fine but I'm getting virtually no hostile mobs on the server. I walked for a whole night with no light around and got about 3 hostile mobs in total. I can't find an area with LC<79 to see if mobs then spawn however.

Here is a video by Docm77 on it; Might help you guys.

Any update news?

Joshua Jones 2013-10-25T22:00:31Z

I still have very limited (almost no) hostile mob spawning running server 1.7.2.

Callum Morris 2013-10-26T16:30:28Z

Is there any more news on this bug? Do you need more proof?

kumasasa 2013-10-29T04:17:41Z

Cannot confirm, my mob farm is working as usual - see screenshot.
(But this an old 1.1 world)

Joshua Jones 2013-11-02T23:32:10Z

Thought I should mention, I actually do have hostiles spawning. I'm not sure if its a normal rates but it doesn't seem as obviously broken as I thought when I last commented.

Talven81 2013-12-18T17:17:13Z

Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.7 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Nicklas Ekstrand 2013-12-25T12:38:19Z

I think I understand this problem now. It's a consequence on how the LC value is treated. If you create a single player world, flat, with the following parameters:

2;7,59x1,15,1,3,2;1;biome_1

You may enjoy the peaceful world. But when you start to add blocks and increase the LC value, mobs starts spawning.

I haven't verified if the LC value was handled differently in the past, my test was conducted using 1.7.4.

Is this still a concern in the current Minecraft version 1.8.1 Prerelease 3 / Launcher version 1.5.3 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
