FTB Ultimate server crash

[GoorBorhn]

Last thing I know, I installed an industrial electrolizer next to MJ golden conductive pipes...
Is there any way I can go back? World is currently unplayable!

Oh crap... MCEdit saved the day! deleted the conductive pipes and machines with it
Can't imagine how it would be if it was another player exploiting this crash and I would have to find it since MCEdit is not updated anymore
Cheers! hope it helps

For future another way that sometimes works is setting the item ID to 0, however this deletes all those items/blocks in the world. However can be used on newer versions cos MC Edit sometimes causes odd things to happen.

In mcedit, is there a way to replace all item ID xx to itemID yy?
I could just replace every conductive pipes to dirt for exemple and /give players with fresh new pipes. Players will have the penalty to reinstall them but at least they'll know where to place them.

That could be an awesome offline tool for server admin! Add the hability to destroy a 5x5x5 cube around last player location (By reading log file) could solve major issues also I guess... just throwing the idea
