yeah but you said you linked stockpiles, did you link your fuel?
sometimes custom reactions go red, it happens in all mods (and modable vanilla buildings for that matter), if you're sure you have everything and haven't made a mistake with burrows or stockpile links then try the manager, he'll (a) fix it or (b) tell you what you're missing

*Facepalm* I didn't link my coke.
And it was a flask! I knew I wasn't completely insane!
So, when I break a spawn location in order to release magma, does it flow straight down, or does it spread out? For example, if I channel a whole, place a support pillar at the bottom, and then a spawn location on top, when I break the pillar, will the magma fall right into the hole?
