So I had an explosion in my MFR Auto-Spawner setup, I was running Blazes when it happened. I also use Cursed Earth for the floor so additional mobs spawn, which I grind for the Essence to run the Auto-Spawner mobs.
Clearly it had to be a Creeper explosion, but how would a Blaze initiate it? I was elsewhere in my base when I heard it happen so I couldn't see anything except the results. I didn't think it was possible for a Creeper to explode in there. Ender Minis used to fight with Creepers and get them to blow up, but I've been running this setup for weeks without any incidents whatsoever. Suddenly, today, this odd event occurred and I'm wondering what happened and why. Oddly, an entire wall of my 9x9 enclosure was gone (mostly Dark Glass, some Marble), however none of the Cursed Earth was disturbed. The explosion must have happened on the floor, no? But the force of it blew up and outward.
