this is the third time this has happened to one of my worlds and its getting to the point where playing tekkit is horrible because i try so hard and get so far, and then this or some other error occurs... please figure out what is happening to cause this. in short what it does is if you load that certain chunk, the server crashes. thanks guys and girls, please help me out :)

You're either on a mac, or trying to pull shit out of a condenser. there's a fix for either of those on the forums.

[aidanhd500]

i was infact, trying to pull shit out of a condensor

[Jay?]

i was infact, trying to pull shit out of a condensor

use the search bar on the top right, and look for "pipe condenser crash" the fix aught to show up there somewhere.

[ChrysWhyte]

actually searching for that only turns up this thread ^^

the pipe condenser crash fix is STICKIED though

[Jay?]

Chriswhyte, you're using the search bar wrong. It defaults to searching whatever index you're on. You probably searched from this thread, so only posts from this thread will show up.

Go to the central index and search again.

[ChrysWhyte]

Ah makes sense. I also see the search button lets me pick boards. Thx that was silly of me.
