/gr setpowerup - Set a powerup's location to the current arena
Fixes:
Fixed arena not returning to the waiting state if the arena is restarting and all players left.
Fixed out of bounds error for holograms and issues with long messages in messages.yml.
Fixed holograms being removed when two powerups spawn at different times.
Fixed the title showing the winning player if all players' scores are zero, it will now display a NOWINNER title.
Fixed an error that occurs with the command-on-win when there are no scores for any players.
Fixed an issue where achievements were sometimes awarded during the game instead of after the game.
Changes:
Instead of powerups being limited, you can now add as many powerups as you want, each with different rarity, duration, hologram, action bar, message, amplifier, material, spawn message, and types. You can also assign any specific powerup types to an arena.
Make sure to remove the types of old powerup in arenas.yml.
