I wanted to suggest maybe looking into another way we could control fire spread than the way now. I've seen it on other posts but fire spread keeps grass from growing but grass is needed for animals like sheep to eat. I never really used the fire spread plugin because of this. Early this morning when I was half asleep and moved my cobble gen, I almost lost my new house because I placed wood too close to the lava and it caught the whole place on fire. I panicked but got it put out and repaired my house after turning off Fire spread.
