Changes:

• You can now change the frequency of attempted Item Ball spawns using a command (as operator). /scoreboard players set #itemballs:spawn_timer itemballs.data 20 attempts to spawn an Item Ball every second, as there are 20 ticks in a second. For example, 5 minutes is 6000 ticks. Make sure to run /reload after running the command to change the frequency.

Fixes:

• Made sure that scheduled functions do not run more than once.
