The simulation is not deterministic but dependent on game speed.
Letting the attached save run on slow and it'll work as expected (lights stay on, constant stream of hydrogen to all generators, backlog slowly builds infront of the valves), let it run on fastest speed and the lights go out.
Expected result: the game speed setting should only modify the frequency the internal state machine is updated, without changing the determinism of the simulation.
Save: Gas Pump Amount.sav
Steps to Reproduce
Load the save - let it run on normal and it works as expected, let it run on max speed and it dosn't.
