Well I don't want to say that you're lying but I don't really understand. As I'm sure I used it as I said recently. It doesn't work as in I can't redeem it or it won't let me in premium servers.
I guess it is worth saying that the server I was playing was private I guess, not a big server with no moderators or such
I don't know how worth it is this screenshot but that's me on the server using an alt from the altening and the mc version is right below the nicknames. The file names of the screenshots gets stores as the dates and times.
Now if you want to accuse me of tempering there's nothing more to say.
I'm not really demanding a fix as I'm just more curious about an explanation if you have any that's all.
Just in case I'm sorry if I've sounded offending.
