What Version of NeoTech are you using: 3.1.0 (1.9.4)

If possible, did you break and replace the block: Whether I did or didn't makes no difference breaking the block and replacing it only delays the inevitable crash. The only way I found to bypass this was to put hoppers above the machines and put them in through the chests above the hoppers except buckets of lava. Still looking into the machine itself is causing a crash which never happened in 1.8 of minecraft.

Please Pastebin.com the crash Report and put link here: http://pastebin.com/UKe0bZpd

same thing occurs also to me with fluid generators unsure how this was missed in testing.

The port was a non official port to 1.9.4. The last version I've had a hand in was the initial port to 1.9 (which was buggy as is). I plan to give some more work to the mod soon. Hang in there, real life is kinda hectic at the moment

Issue was regarding the new NBT saving from forge, fixed in next release
