Ok, that makes not sense. Thanks for clarifying!

I would agree with you, but it has never stopped the reaction previous to the 0.6.1 update.

I am unsure if the height is affecting the reactor or not, and will be unable to test it until I have found more gold.

Yeah, this happened to me, iOS 6.2, iPhone 5. I flattened off an area, made the nether reactor. I shut the game off, and then came back. The area isn't flat anymore and the tower of netherrack is gone. But the pieces of netherrack are still in my chests.

I tried it again on a creative world, but I made a sandstone house this time. I exited, rebooted,and everything, and the sandstone house is still there this time. Maybe it only affects survival?

Looks like it still works...

Were the diamonds the only thing you had in your chest? And are the rest of your chests still perfectly fine, or did they get emptied too?

I didn't know this was a glitch! I had four melons on each seed!

Yes, other world maps that I have started. Sorry for not making that clear!
