As mentioned in the title whenever I place a red alloy wire piece/framed red alloy my world crashes and it brings me back to minecrafts title screen! Ive never seen a bug that only crashes the world not the whole game .. btw I am on Minecraft 1.7.10 and I searched for a log file and this is all I found!
Also if you go down a bit you will find that I requested 64 framed red alloy via NEI but when I placed it the world closed and after that the world becomes unplayable (Never open again).

Can you narrow down the mod list?

You mean from the game or the log above?

The game, so we can try to pinpoint the cause

Ok I will try it out and come back shortly

I have come to a conclusion that one of Chisel or InvTweaks or Jabba or Waila is causing this problem!
And I am thinking its Waila unfortunately but I will need some time to confirm because my java is now updating and I can't do much!

It is indeed Waila!
It seems the new version is bugged because I had issues with the impossible object from extra utilities and now after I removed Waila It works!
Thanks for helping man .. Really saved the day!

Good to know it's worked out, you might want to let the Walia dev know about this if you haven't.
