first of all I want to say THANK YOU FOR THIS AWESOME MOD! I hope you enjoy my little donation yesterday
Now here comes my suggestion:
When I build a reactor and I surround it with Reinfored Stone there is no risk anymore when I overheat my reactor and it explodes. The only thing I loose is the reactor itself (ok, its quite expensive but once a proper industry is setup its quite easy to produce a new one). So my suggestion is, you make a reactor accident a little bit more annoying (but in a funny way):
When a reactor overheats (and currently explodes), instead of overheating let him smelt. Replace the reactor blocks with a sort of radiation slime source block that behaves like lava but is green. In the enviroment of the radiation slime every living creature gets damage (except slimes). Also in the enviroment of the radiation let slimes spawn.
So players really have to clear up the mess they caused
Another further going idea would be, to collect the slime and build "dirty bombs" which exlode like an A-Bomb but spawn a lot of very big slimes as well
I would be very happy if you take my idea into consideration or answer me why you dont like it.
with best regards,
