So I just discovered that I can't run this simple command from a command block:

/tan setseason mid_winter

Turns out that
"[21:54:35] You must specify which player you wish to perform this action on."

I tried providing the @p argument in random places between /tan, setseason and mid_winter - nothing works.

Can't we just assume that when there's no player specified while executing, just let it run the command as world/server? I hope there's a fast and easy fix for it. It really messes up my timekeeping.

Does anyone know if the problem persists on newer versions? (1.11+)
