Achievement Glitch

[Fnnythe3hd]

I'm honestly not sure if this is a glitch or not but:

From this you can see that it says "Unlocked Achievements: [72/71]".
Is this a bug?

Nope there was a test achievement which is no longer in the list but some people still have the 72 out of 71 due to this reason(This is from what I have heard anyway)Hope it helps

I think this is a glitch but should soon be fixed by the developers .
