The fence gates right next to it appear to have caught fire, something I only noticed while looking at photos. But once the fence gates are gone the lava will be 1 block from more wood on the other side and it will not catch on fire which I would normally think should light.
The picture didn't seem to work in the comment format but you can still see the cords and seed so it's fine. The lava source block is higher than the wood that won't start on fire, and there is more wood on the other side that is at a different y level that also doesn't catch on fire. The lava that is on the wood is also on a different y level than the wood under it. While the wood on the other side is not touching it is within a block so it should still catch on fire. There are also several other spots in the mine that have lava touching wood and they catch fire like they should.
Kind of, except the blocks next to it did not catch fire either. Perhaps I didn't wait long enough but it isn't something I need to pursue.
Thank you.
I don't know if that was bugged or telling me there were different ways I could make the same recipe. When you hover over it it will show an image of the crafting recipe and it will alternate between the two recipes.
