    • Confirmed

      When you do an operation between 2 'empty'* scores the first score will receive a score of 0, even though you get an error message: "No <name> score for <player> found". This score won't show up on the sidebar until you reopen the world or update the display slot.
      *: when you created a score but you didn't set any value for an entity

      Steps to reproduce:

      1. Create 2 new scores
        /scoreboard objectives add test1 dummy
        /scoreboard objectives add test2 dummy
      2. Display the first score
        /scoreboard objectives setdisplay sidebar test1
      3. Do an operation (notice that the sidebar didn't change)
        /scoreboard players operation @p test1 = @p test2
      4. Update sidebar (notice that now your score appeared on the sidebar)
        /scoreboard objectives setdisplay sidebar
        /scoreboard objectives setdisplay sidebar test1
