Minecraft Forums

So I was playing minecraft the other day, and all of a sudden it closed itself and the launcher popped up. It didn't say it crashed or anything, so I just restarted it and tried to open my Single Player game again. But that time it did crash, and I have no idea why. I was playing for at least 20 minutes before it crashed, and for a few hours the day before and everything was running normally.

Here is the crash report from me trying to run it again today:

I was using LotsOMobs up until recently, but my game lagged a lot so I deleted it. But I played it for a while after I deleted it and the game was fine.
I also just deleted everything and re-downloaded all my mods again. That is the most recent crash report from after I re-downloaded everything. It is only when I try to play my main Single Player game that it crashes, I can start a new world or play a different saved single player game without it crashing.

If anyone has any suggestions or anything that may help, I would greatly appreciate it.

This is the 3rd topic I've posted in a few days, I really want to get this fixed, its really driving me crazy not being able to play.

Yes! Everytime I try to play it it crashes before it even opens.

Okay, I don't really know much about this kind of stuff so...
What's MCEdit?
The only thing I can think it would be is the old portals from when I had LotsOMobs, because I think I'm close to where they use to be, but I played for quite a few hours after I deleted it and I'm not sure I went close to them since I deleted it.

Okay, I found MCEdit, but I have absolutely no idea what I'm doing. I selected a bunch of stuff that was around me and deleted it, and moved back to where my house is. But I'm not really sure if it actually did anything. But I hit save on MCEdit and closed it and tried opening my game on Minecraft, still crashing, This is what the crash report says now, not sure if its any different than before:

I did everything you said, but it didn't work. When I did that and reopened Minecraft my game file didn't even show up on the SIngle Player Game list. Thanks for trying to help though!

Hi,

I've got the same issue with other mods and MC 1.6.4:

http://pastebin.com/XcpGYYyP

http://pastebin.com/swct2pJN

http://pastebin.com/aFQiX3EH

It seems to be related to specific locations. I could reproduce the issue (at least sometimes) by walking the same path from the spawn area to a specific location. Then I normally got the crash.

My solution was to go to the world folder (in my case on my server) and delete everything except for players, level.dat* and region files.

But I cannot tell what would go wrong because of this. At least the server was then running for some time until it recently crashed again multiple times.

OMG! It actually worked! I had almost given up, but that worked, and it doesn't seem like anything's different! Thank you so much!

Quote from Icke2002

Same issue here, i have al lot of mods installed (over 100) )))
It freally sucks - so I have MCSave Installed so i could reentry my world.
So yes its a structure Problem - but I have no idea which mod try to build a structure.
Here my Crash log http://pastebin.com/BjyFR0um

It's probably GraveStone{2.4.1} [GraveStone] (GraveStone_2.4.1.zip)

See next post

Hello,

what I could confirm is, that the GraveStones mod (version 2.4.1) makes worlds unplayable as soon as some apecific structures were generated in villages.

http://www.minecraftforum.net/topic/1711328-164-smp-gravestone-mod-v241/page__st__400#entry25710771

There's a file called village.dat for each dimension which contains information about all (already discovered) villages and their structures. As soon as someone comes near a village with one of the GS structures, the server will crash.

So one should disable this structure generation in the mods configuration and remove these NBT entries using NBTExplorer (or something else).

The easiest way to do so is probably deleting the file village.dat, but I cannot tell which side effects this could cause.

Screenshot (NBT)

Configuration section

GraveStoneMod has fixed this with 2.4.4 (well, I havn't tested this yet, but NightKosh lists it as fixed)

The consequence of deleting village.dat would principally be if a village was only partially generated before the village.dat was deleted. When the village is regenerated in the same position (it will be) it will get a new structure list and hence layout and thus, the old and new buildings won't line up - especially where the cross chunk boundries. The village.dat data is not needed for generated chunks (which can be verified using GSMod - with a game that is crashing, delete the village.dat, log in (successfully) and visit the village, log out and replace the village.dat with the old (faulty) one. Log in and the game won't crash as the chunks are all present.

I believe Necromancy 1.5 is doing this as well.

The VERY FIRST crash lists it failing to generate a necromancy village structure.

After that it's just generic structure gen errors, kicks, and sometimes full server crashes.

mine just wont load into the world for single player i really havent tried multiplayer but i try to wait for it to load and still after like an hour it still wont load do you guys thinki should just reload the launcher

deleting all but level.dat, region, and play data fixed my 1.7 world! thank you random people on the internet. lost a few diamonds i had in my ender pouch, but NEI is a thing

NetherDungeons 1.2.1 has the same issue. After I delete it everything is right again.

I just registered the forum to report it.

I'm having something similar i am playing 1.7.10 Forge.

Here Is The Crash Report.
