Reimbursing terraforming is the tricky part. There is simply no way to know how much or where an individual character or a corporation has terraformed. Pretty much the only thing we are able to do is a fair approximation based on gamma activity. So the plan is to check which corporations ever had a gamma terminal in the past (counted up until today, to avoid abuse), and we’ll give out a package of terraforming charges for each terminal they have ever placed.
