Cant use skill reset book on humans might skill

Currently you can't use the Skill Reset Books on skills that are first or in a middle of a tree. You can only reset skills at the bottom/last skills of the tree that you obtained, working your way up. I don't know if @Daneos is notified about this, but I hope he fixes it soon.

P.S. On a much earlier update, he made it so that you can't reset skills when you have obtained the next skill in the tree, because people were abusing the skill reset books and removed all the useless skills working their way to the best skills and also having spare SP to use.
