This occurs when you put stacked Weed Ex in a Crop Matron.

As soon as the chunk gets loaded, the server crashes.

Luckily, we fixed this because one player noticed this relationship and notified us of the location of the crop matron and we rolled back the block place even of the machine. Now everything is fixed.

This probably is a low priority issue, but I am wondering if this occurs with the Technicpack as well. If that is the case, I will be making an error report directly on the Industrial Craft Forums.

I've gotten the same problem. Unfortunately, now that I've identified it, I've no way to get rid of it. No map editors I've heard of support Tekkit and I can't remove it manually as the server freezes when I approach it.

[Mastergalen]

McEdit works for Tekkit.

What you can also do is if you know the coordinates of the area, you can use an online calculator to tell you which chunk it is in and then try and deleting those chunks manually from your world folder.

Thanks for the prompt response, didn't know about McEdit. Now I can safely get rid of it.
