"You need to be a VIP to do that"

/vip doesn't work for me, says i'm not VIP :/
if a screenshot is needed, tell me, though it's really easy to picture the situation. (for those who tried /vip while not vip)

Also I remember a few months ago when I /vip (without another word) it said i'm not VIP, it's a small side bug with lifetime, I think, does the same today.
