Engineering Issue

I am having a issue where when I use my + objects from, well anything, they are not being added to my skill level. I have been stuck at 47 for at least 2 weeks, my skill should be, at the minim, 53 I would say. Please figure out what is wrong and award me the levels I deserve.

unless you clarify what the “+ objects” are, i’m assuming you’re referring to the ones that grant knowledge points and not skill points
