It has recently been brought to my attention that the terraforming facility in the facilities.txt file only repairs damage to a colony and does not actually raise the habitability rating above starting. In the next version of the Bacon Mod I will add terraforming so that this facility will raise the habitability rating. As always, this will be an optional feature implemented as follows:
In facilities.txt you have the terraforming facility (entry #9)
9, Terraforming Facility, 7, 0, 9, 20000.0, 2000.0, 200, 0, 0
The last two values after the repair rate (both zero) are unused. In the Bacon Mod they will be used for 'terraforming rate' and 'habitability cap'. The default values for the Bacon Mod will be 500 and 80
9, Terraforming Facility, 7, 0, 9, 20000.0, 2000.0, 200, 500, 80
This means that the habitability rating would improve up to a rating of 80, where it would stop. The improvement is semi-asymptotel, meaning that the rate of terraforming will be quicker when far from the limit and slow down as approaching the limit. It's not a true asymptote so you will eventually reach to limit.
For those not wishing to use this feature, simply don't make the changes to the terraforming facility.
