I didn't notice this issue until after yesterday's patch - not sure if it existed previously. When you open the skill gump and hover your mouse over one of the skills, the wrong skill name is displayed in the tooltip text box. For example, I had the "wild" tab up in the skills gump and when I moved my mouse over the animal lore skill, one of the bard skills displayed in the tooltip text box. I tried some other skills and they all displayed some kind of mismatch.
