Well, finally dig deep enough to find the offending mod. It was Mine&Blade Battlegear 2. Luckly, the error was already reported there. https://github.com/Mine-and-blade-admin/Battlegear2/issues/124 Cheers for the help!

QuarryPlus 2.0-RC4 launched in its own instance with forge .1219 only --> Works HardcoreEnderExpansion 1.6.3 launched in its own instance with forge .1219 only --> Works Artifice 1.1.4-296 launched in its own instance with forge .1219 only --> Works Launching custom modpack (380 mods) with forge .1219 --> Works Launching ANY/ALL of those 3 mods inside that custom modpack instance --> crash with same pattern as in the first post. I'm pretty clueless why... Had forge and/or my instance folder been corrupt somehow?

I found my offending mod: QuarryPlus. Artifice 1.1.4-296 launched successfully with forge .1219 HardcoreEnderExpansion 1.6.3 launched successfully with forge .1219, although chylex did not recommend this forge version All in all, thanks for assistance.

Yes, works like that WITHOUT any mods, bar forge. Can I ask, what is the cause of my crash so I can further troubleshoot and report to mod authors if found the issue?

After upgrading to the Forge version 10.13.1.1219 from .1217, I no longer can start the instance without a crash.

Yeah, I apologize for that. It's not of any use anyway, since using that link will net you a corrupt world anyway. But I understand the issue. Any soul, willing to troubleshoot this issue, leave me a PM here or on the MCF.

I've compressed the saves, mods and config folder as-is for usage of resolving the issue. It is located here: [redacted] Cheers! Edit by moderator: Please PM link. We don't want to be giving the impression that we're redistributing stuff.

//SIDENOTE: crash does not happen in the creative Superflat world. How come? Ok, that's a start. Now to figure out all possible mob spawning mods in this pack. With the use of Mob Spawning Controls 2 I gathered a list of possible mods, that spawn anything in the world (not block related). Vanilla AnimalBikes ClientSidedHorseMod QuieverMod Natura Biomes O Plenty MineFactoryReloaded Forestry AwWayofTime (Blood Magic) Golem World Hardcore Enderdragon TConstruct Thaumcraft Mystcraft TwilightForest MutantCreatures NetherOres OpenBlocks PetBat Sorcery Camping AIBlock Next step is checking what actually spawned on the time of the crash. 21 entities from the log, which are as follows; [*] EntityQuiverModSkeleton [*] EntityZombie [*] EntityQuiverModArrow [*] UnglitchClientPlayer [*] EntityTFNagaSegment [*] EntitySheep [*] EntityEnderman Now, I am wondering, there are multiple EntityTFNagaSegment spawns with in-game name of unknown and a serial number behind it, does that cause this sideeffect? Also, Vanilla skeletons are being transformed into modded zombies, which could cause packet corruption? So, my first bet was removing Twilight Forest, which fixes nothing, since loading the world cause the game to crash with "Shutting down internal server". Next try was removing only QuieverMod, aka Better Archery. The world still refuses to load when the mod is removed. Next on my list is, completely removing ALL the mods and check, if the world is completely corrupt. Creating a new instance in MultiMC5 (thank devs for it), I created new 1.6.4 environment without ANYTHING (no forge or similar stuff), pasted the saves folder into it and started the game. Which resulted with a following crash; http://gw.minecraftforge.net/yrRi Retrying with Forge installed. Game launched fine. Opening the world. World loaded. There were immidiately 2 zombies in my face. Thinking about what the next approach should/could be... Some googling on the internet I came across a nifty tool called Minecraft Region Fixer. No hopes for it to actually do anything, but I'm thinking outside the box. I have a corruption in my world, and this is trying to expose that. I am still unsure what or why causes the crash and world corruption. As expected, the tool did not find any chunk corruption or file issues. Now, I am clueless, how to proceed. Help?

I apologize for the Dropbox, but I cannot post a pastebin of the forgemodloader-client-0, because it is exceeding character limit and/or timing out my upload request. Did fix the copy paste from the MCF post with proper links though. Cheers.

Greetings! I've tried to assemble myself an advanced private modpack with interesting topics that would suit my play. Obtained all the mods, installed them, resolved id, item and biome conflicts, started the new world, changed the gameplay settings, was ready to explore and enjoy. Then the FIRST midnight comes, and BOOM goes the fun. That thing keeps happening. New world, new seed, first midnight, the end. The following errors are what plagues my game. I cannot open the world anymore, it is basically corrupt to my knowledge. I've tried searching WWW, but alas, there is only a single same report available, and it links to DivineRPG mod, which I do not use, have not installed, or have it present on my PC. Further invistigation lead me to the Forge patching NetClientHandler function, that is why I am posting this here. Description: Unexpected error java.lang.NullPointerException at net.minecraft.client.multiplayer.NetClientHandler.func_72519_a(NetClientHandler.java:952) at net.minecraft.network.packet.Packet24MobSpawn.func_73279_a(SourceFile:87) at net.minecraft.network.MemoryConnection.func_74428_b(MemoryConnection.java:89) Modded MC 1.6.4, Windows 7 64 bit, latest (as of posting) Java, GTX560Ti, i5 2500k, 8 GB, SSD. Crash report located here: Forge Pastebin ForgeModLoader - Client 0 located here: ForgeModLoader-client-0 log Any help would be greatly appreciated! Cheers!
