Apparently, what happened is that lava now can burn up to 2 blocks away. So, if you have an open lava pit, a space (grass I suppose), and then a wooden wall, it'll light that on fire.
Yeah well my lava was in freefall with one block seperating it and a wooden floor, (A HUGE FUCKING 3000+ PIECES OF WOOD FLOOR) bitch notch
