The scoreboard and teams was not save after reloading the old world!
How to remake this bug:
Load an old world (for me 1.9) in 1.13, make a teams/scoreboards , save and quit and reload the world and see your scoreboard that is no longer there!
I want to remake an old map for the 1.13 and this bug is blocking me in my works!
