Aw, excellent? That's sweet. All I did was play with the vanilla barrel code a little bit, I don't even know anything about scripts!
I wonder how long a barrel of steam would stay warm for.
I saw your thread on my OG mod, I'm back on Factorio for another playthrough, so I might polish it off at some point and credit you for the steam, so everyone can come blame you when the steam cools off back into water!
I'm glad this silly little mod made you happy, I appreciate it.
