i was messing around with the effect and enchant commands to test for bugs when i got bored and tested scoarbord for bugs and i found a major bug: after creating a dummy objective changeing spawn dieing then removing the dummy objective (was displayed on side bar in team pineapple with color gold) and adding a new objective with the same name (swag) but in all capitals after telling minecraft to set display it would not set the display. muliMC report attached.
