Chisel - block has no texture - causing a crash - corrupts world probably

[CriticalRocket]

Hey there!

I'm playing with a technic modpack called The 1.7.10 modpack.
I came across a block without texture, which is making my world/game crash. I posted about it in the modpacks thread but I guess I should post it here aswell :p

Post I made there:
xJon/The-1.7.10-Pack#468

As you can read, I've managed to more or less fix it myself. But this is still a weird bug which should get adressed. If you need more information, just ask :).

Running mc version 1.7.10 on java 8 64bit. Windows 8.1. More info is in the pastebin logs I provided below.

I just copied everything I said there:

Hey!

I was mining yesterday, and I came across a chisel block without texture, showing the error texture (4 squares on each side, of which 2 purple and 2 black).

I didn't think much of it so I mined it, it dropped with the same error texture and I moved on.
Some time later I suddenly crashed, and now I can't get back into my world.

I don't remember at what time this happened, but I've got 1 backup each hour. So I tried each of these in SSP, and each of these spawns me with 'you are death' on the location where I stood when I mined this block. I can see the on the background block in the 'death' screen, back in place. I remember certainly playing more after mining the block, and I don't remember dying there.

My friend continued playing a bit after that yesterday whilst I was looking for a fix, and he played a bit whilst I was at school. So I just tried entering the most recent version of the world in SSP, and that world I can't enter at all, it just crashes my game. That happened with my worlds yesterday as well, but now each of my backups atleast allows me to enter the world.

So you'd think "hey, you can enter your backup world, you died, just go get your items and load the backup!". Well, I just tried getting my items but my world crashed when I got into a like 5 block range of the 'corrupted' block. Going to try again in a bit.

Logs of my backup world crash:
-client.txt: http://pastebin.com/faYWrWT5
-server.txt: http://pastebin.com/SQGtiuXn
(also, my client sometimes gives me a -server.txt error log.. I dont know how why.. but its different from my -client.txt error log)

Log of my most recent world, which crashes at loadup:
-client.txt: http://pastebin.com/MTEfVZr7
no server.txt error log.

I'm not sure on how to tackle this problem. I tried finding the block with an NBTeditor but I couln't find it, I don't know where block data is located.

Any help is greatly appreciated!

Oke, so I tried out some stuff.

-I've got Aroma configured to make a backup when I stop the server. I stopped the server when I came home a few hours ago.

When I load the world directly from my server into SSP I crash at spawning.
When I load the world from the backup I don't crash!

Thats weird because it should be exactly the same :/
The way I crash on the server world is weird aswell.
When I load the world, after a while it goes back to the main menu, stays there for 0.5 seconds, then goes to black screen, and then I enter the world. I see a black screen with an empty toolbar and an empty minimap, and then it crashes.

When I load the backup I spawn in a location I wasn't at at first, as I said in my first post, it's where I stood when I mined the corrupted block. Well, I 'spawn' there, I'm instantly dead, or I was dead just before the backup was made, I'm not sure. I only know that I get the 'respawn' screen on loadup.

When I respawn and walk to the location, everything is fine. But when I look at the block, as in, aim at the block, I crash. Maybe it has something to do with the block tooltips? (block name and 'can I mine it yes/no' information on top of the screen).

I don't know what the cause of this is, but it wasn't happening yesterday..

I'm going to try and blow the block up with some TNT. I don't remember which kind of block it is exactly, and I cant mine it or anything to find out now. I only remember that it was from the Chisel mod, and I remember coming across another block with the same error texture yesterday aswell, like 5 - 10 minutes after I found this one.

P.s. as you can see I'm using default minecraft textures. I was using optifine yesterday when I first crashed, but I removed it afterwards.

EDIT:

I just went into my world and picked up my items. It seems one of the corrupted blocks was in my inventory! This all is very strange..

EDIT 2:
World wouldnt load anymore after restarting the launcher (wanted to make a backup before I tried destroying the block). Now I can't launch the game, got the launcher issue where it doesnt launch the game when you click 'play'.

Pfft, this is starting to get really annoying.. ><

EDIT 3:
Seems like minecraft was still running in the background (just took a look at task manager). I guess thats a good recommendation for other people with the launcher problem haha :p. Working again now. Sorry xd

EDIT 4:
Yeah, my world is currupted again now. Or my character in the world is. Point is: game crashes when I load it. Only reason I can think of is maybe because I'm standing in the same chunk as the block now, and maybe that makes the game crash when its loading. Going to reload from the backup and try to remove the block.
