My mastery progress bar in the bottom of the screen very often shows incorrect mastery leveling progress. Few times already I have maxed a mastery, but didn’t know about it, cause on the UI it seems that there is still grey bar left to be filled. This way I have lost XP because I didn’t train the completed mastery.
Please take a look at the screenshot below which depicts the issue. You can clearly see in the hero panel that I have 100% of the mastery trained while in the bottom there is still a lot of XP to be gained
