A couple of hours ago I completed Advanced Logistics / Pact Commander mastery track (using up the last of my mastery points) and then applied the 9th Mar patch bug fixes so I don’t know which has caused this.
Now while in core Tyria my mastery exp bar is empty, stating 0/0 when moused over, and has no icon in the far right. Clicking on the far right area opens the mastery tabs but with nothing selected to work on. Further selecting the Legendary track does display the information I expect it to so I hope this is just a display issue and not functional but I can’t test that until I get more points.
This does not occur in Verdant Brink where the Maguuma exp and icons display as usual.
As stated this occurred either when spending mastery points or at the patch fix for my lvl 80 Sylvari Guardian though the display is the same for all lvl 80 characters.
Additional: quick check with events shows the exp particle effect moving towards the bar is also missing
