I was just about to report this, the exact same thing has been occurring with me. For about a week now I have not been able to smelt gold in a normal furnace or blast furnace.

This issue is not resolved, so quit saying it is on everyone's reports, it has been going on for weeks.

the glitch happened in the 16w03a snap shot just the world was created at that time

1.6.4 at the end of 1.7 snapshots,

I have the same problem, and here is the game output before it crashes:

I Believe it has to do with block updates. and its noT because if the other pistons because I had the stuck pistons on all the time and nothing.
