I didn't even know that you
could light Netherrack on fire.
The only time I've ever seen it was atop the Money Bin.
That would be awesome if Brad feels so inclined. I'd go up and replace every damn piece that's burning now. I'll try and get on there in the next hour and do a count of what's burning, maybe take some pics for reference (I'd like to keep it as close to original as I can).
[edit]: High 500's - low 600's. ~85% are just single burning blocks, so it may be best for me to just replace trunks where there are any. That would alleviate the split-trunk blocks catching fire from below.
