Here's the report.

And no, I was playing on my survival world.

Is this a server or a singleplayer world?

What happened?

You most likely have a corrupted world.

How does a world get corrupted? Also, is there a way to fix this?

Alright, I got the world back, but how do I fix the corruption?

I found out what the problem was, and how to reproduce, but this turned out to be intended. (stairs don't allow redstone connections from below them)
