Gas filters producing extreme temperatures.

For no apparent reason, two newly-built gas filters just overheated by somehow heating up their output pipes.

Here's where the molten rock (and power wires) re-solidified down below.

And the input gas streams were not insanely hot.

This save is from when the first three screenshots were taken

Re-loaded and tried building the pipes out of abyssalite (nothing happened) then disassembled and replaced them again with more igneous rock to see what would happen, and... now they're getting absurdly cold.
