Fission reactor exploded when it shouldn't
​
My friend was playing on our mekanism server when our 5x5x6 reactor exploded. It killed him instantly. The reactor had an emergency shutdown for High heat, Low fuel and excess waste. But that didn't trigger somehow. We tested it before and it worked. The reactor and the turbine were in one chunk. The shutdown was also in the same chunk. Only the fuel production was in another chunk. But he was in the base and everything was loaded. We also had a shutoff if the power was full but he disabled that for more nuclear waste (the reactor shutdown was still on). We think the turbine got full of steam and energy but we don't understand why the emergency shutdown didn't trigger.
We built it like this:
3 Redstone ports:
High heat
Low fuel
Excess waste
That sent redstone to a piston. One in front and below was a redstone torch so it sent a redstone signal to an activation torch when a black was placed. So when the ports triggered the piston would push the block away and disable the signal and reactor. Does anyone know what could have caused it?
My video above shows how I built it. (I built this in creative on a singleplayer world)
