A visible boss bar with any max and value appears in the same state as a value of zero, regardless of the value and max upon exiting the game. Changing the value does not fix the issue, but setting visible to false and then back to true does.

What I expected to happen was...:
Boss bar would stay consistent upon reopening

What actually happened was...:
Just needed to make it invisible and then visible again

Steps to Reproduce:
1. Create a boss bar, set any max, and set any value.
2.  Restart the game.
3.  Boss bar should appear empty regardless of value. Changing the value does not fix, but making the boss bar invisible and visible again fixes the issue.
