Typo in /achievement give

Unable to reproduce. Exactly what did you put in the chat box before pressing tab?

I just did /achievement give 123 to find out how to use it

Pressing tab after that does nothing for me.

No, you Don't press tab, you press enter. It says "Unknown achievmenet or statistic" or something like that.

Oh, sorry. Confirmed.

Confirmed as well, voted for since in any case it's a mistake.
