Nasty things that can happen to you.[]
Ok so I was playing some time ago on Conquest beta Tycoon (Number of inhabitants) mission.
I got pretty far around 1500 executives and about 13k people. I had just transitioned from coal power to nuclear power- I was running my main island with 2 nuke plants and just demolished every coal power station. I had steady maintenence unit and control module production. so I wasnt' worried about nuclear / technological disasters at all. Before my transition to Nuclear Power I was experiencing the natural "bad Ecobalance" as tycoon, where ecobalance was around -160, nothing too serious. After transitioning out of coal power ecobalance rose to around 0.
However, the game had already registered my bad ecobalance in the past and sent a devious Tornado on the map. Notice this happened AFTER I already improved ecobalance to about 0. So I thought the worst risk of Tornado was over...
Tornado came closer little by little to my main Island (At first it was even a bit offtrack) What happened next is a disaster.
Tornado swept only a small corner of my main island, but that corner proved to be the most vital!
The thing is that I had ONLY 2 Nuke plants to run everything smoothly on the island. Now the Tornado hit my nuclear plants, which at first I didn't mind I just quickly built 2 more in another corner of the island. Now the nuke plant has plenty of life and wasn't destroyed at first, BUT first one catched a FIRE.
Obviously I couldn't delete a burning building. In addition the burning nuclear plant stopped producing ANY energy, dropping me about -400 in energy. Shortly after, the same happened to another nuclear plant, dropping me to around -900 energy, I desperately tried to EXTINGUISH the fires with my Fire stations, BUT to no avail, Fire stations don't work in -900 energy conditions.
The tornado went away but the 2 Nuke Plants were burning (plus some expensive Tech structures were destroyed) the other 2 nuke plants were not operational due to lack of Fuel rods, which I couldn't import or deliver from trenchcoat the 2 burning were full of rods though. I couldn't extinguish fires because energy shortage. And even though I had small production of rods, the reactors were WAY too Slow to operate on 100%
The only thing I could do was to build again a massive amount of coal stations to try to extinguish my nuke plants, which I did.
This however was too little too late, Both my nuclear plants burnt to destruction leaving me with 2(!) Nuclear plant ruins both generating -100 ecobalance each + huge no construction zone. Dropping me back to -600 ecobalance and -900 energy
That was really the worst case scenario with nuke plants and Tornado hitting them. Next Time I will certainly delete any plants if there is a chance of a Tornado hitting them.
