I suspect that efficiency refers to the fuel consumption.

The solid fuel you put into the mine will be used with that 42 % efficiency, same with all things that consume fuel.

Löschkalk would be slack lime

For the first game I would also suggest to disable the biters because it can be very frustrating.

Thank you, I just found out that it works without the rubber.

Love your mods.

Thank you again.

Hi,

I searched to forum but was not able to find an answer.

I am at the stage where i need rubber to advance. In order to produce some i need a multi purpose cracker.
That however needs a lab. All of a sudden my labs need rubber to produce them?

Is that meant that way? Do i need to tear down ...
