Fire

[Pascali]

You have to build some Firepreventers to be able to kill fires.

If you have a bad bots-transported-units vs. belttransportet-units factor - you will have bots who are falling down and cause a fire.
You have to prevent the player from putting somethin on belts and filling it in fosses only to do it vice versa. For having transported goods and having a better bots-transported-units vs. belttransportet-units factor. Or you use a bots per m² factor.
