1. 1.1.5, 1.20
2. After server restart, actively-cooled reactor quickly consumes coolant (water), and then explodes.

I've noticed after restarts that I hear an explosion coming from my reactor room. I have meltdowns and other dangers turned off (Due to stability issues). It turns out that after a (dedicated) server restart, the water begins getting rapidly depleted, faster than my water source can keep up with (~800mb/t I believe). The reactor will quickly have insufficient cooling and "explode". In my case, the only penalty is voiding the inventories (fuel and depleted fuel).

I believe problem only happens on restart. Once the explosion happens, the port will begin accumulating water again, and adding fuel will not cause it to overheat.

I have no idea what's going on here. I'm not actually convinced the reactor consumes water at all after I break/replace the controller. So maybe the on-restart behavior is (somehow) the correct one and we're expected to provide even more water than I already am per tick. That would still mean the water consumption is broken after place/replace of controller however (including if the controller "explodes" but explosions are disabled)

I think this may be related to #152 : after server restart, even if the reactor doesn't have a redstone signal, it immediately begins very quickly eliminating coolant. Fuel might need to be in the reactor to reproduce.
Breaking the controller and replacing it corrects the state (if you can do so before meltdown)
