XP bar is frozen at full
This isn’t a bug. You finished gaining the experience required to complete that mastery point. Now you need to go into your hero panel, go to the bottom tab “Masteries” and spend a mastery point to unlock that mastery. When you do that, it will allow you to train a new mastery.
Have you checked your masteries and unlocked them? It will not go up unless you “spend” that level on a mastery.
If your bar is full, and you’re level 80, that means your current mastery track has been completed and you need to spend mastery point(s) and then it will reset the bar and start levelling up the next tier.
The reason you’re not experiencing this in the expansion maps is because your Maguma masteries are separate than the standard Tyria masteries and your current Maguma track has not filled yet.
Check your mastery tab in your hero panel (H) and see if you need to spend a mastery point.
