I have this weird bug now in 1.4.2. When I walk over this group of blocks, I suddenly catch on fire. For no reason. I've even broken the floor too make sure there's no lava behind it.

Does it keep happening? Can you reproduce it? If so please include a copy of your world describing where in the world you experience this issue.
Sorry for taking too long. It stopped a few days ago. Originally, on that place, there was redstone. It was soon after I upgraded to 1.4.2 and installed Optfine, so it might have been this =/
But now everything is good, thanks
