When a scoreboard objective is created (scoreboard objectives add example dummy), all players scores are set to '0' by default.
Then a command is used (e.g. /tp @a[score_example_min=0] ~ ~1 ~) and the result message is 'the entity UUID is provided in an invalid format'.
I cannot tell what the problem is, whether it is player parameters are broken or players just don't have a scoreboard value assigned to them. This is breaking a lot of my maps and I would be grateful for a fix.
Thank you.
Its because the scores haven't been affected therefore the commands can't tell if they have zero in the objective. you have to manual set the score to zero first
