When a Starfinder character hits 5th, 10th, 15th, and 20th levels, it increases four attributes. These increases are by +2 if the attribute is less than 18 at the time, +1 if they are 18 and higher.
This is supposed to use the UNMODIFIED attribute score. It isn't. If you have a personal upgrade set on an attribute that increases its value past 17, it makes adding a +2 to that attribute unqualified. I have had to unassign a personal upgrade to get it to do it correctly.
