This issue may be a singular issue caused from one problem or multiple. I will give a example of what i was doing and what happens when i do this now. I created a system that would clear "Player Offline" from the scoreboard by using a operation command. Score "a" would be the internal actual score of the player and score "b" would be what displays on the scoreboard. When i take points from score "a" it translates it to score "b". The system was to remove objective "b" and then add it and replace it again so that it shows score "a" When a player leaves the game and i remove their "Player Offline" it removes the data for score "a" and will not display it on score "b" I do not know if this update now purposely clears data for scoreboards upon leaving but i hope it can be fixed. This also happens when i add a score to myself, it clears my score for score "a" and displays myself as a "Player Offline"
