I noticed a crash every time I tried to play an alloy furnace (The version was 1090)
sorry btw it was caused when placing an alloy furnace next to a industrial craft 2 iron furnace.

A new build is on curse that fixes it

Crash report and logs please

You didnt happen to place it next to a door?

worldObj.notifyBlockChange(xCoord, yCoord, zCoord, blockType); is causing it to crash. I will take a look. That is very odd. I don't think I need that line so it should be an easy fix

sorry if this bug was already solved

No, it wasn't. Thanks for the report, we got it fixed now ;)
