The bug
'/scoreboard players reset * objective' does not work. The command prints java.util.ConcurrentModificationException in chat and resets only one player's score for the chosen objective.
Expected behavior
All players' scores are reset. The objective is empty.
How to reproduce
- Create an Objective with multiple scores (players or fake names)
- Use the command /scoreboard players reset * objective
Note: I noticed that in rare cases it works as intended, resetting all scores. It seems to work after setting multiple fake scores with the * wildcard, e.g. using /scoreboard players remove * objective 1, when fake players exist on other objectives. I am not sure if there is a pattern to this behavior though.
