I'm trying to make a command for a hide and seek map but I'm having this problem. The following is the command I use:
/effect @a[team=S] minecraft:slowness 20 10
The selector @a[team=S] doesn't work. It says:
Selector '@a[team=S]' found nothing
This should work because I made sure someone was on that team (me) and the team did exist. Though no matter what command I use it still comes up with the same result. The map won't really work without it.
