In one of my original posts I had a skill in my skill tree that showed the wrong icon. It was a minor issue and we were working on a much larger problem at the time but we never figured out what had caused it, I just remade the problem skill in a different place in the database and used the new skill ID. I seem to have duplicated the bug.
Possible Bug: I copied and pasted a skill and then altered the skill's icon. I then made the skill tree and placed the skill in the skill tree and the wrong skill icon is now displayed. The icon of the copied skill is displayed instead of the newly altered skill's icon. I just thought I would let you test this and see if you could duplicate the bug. As for me I am just going to copy this skill and paste it and use that skill id instead. That was my workaround last time.
