achievement glitches

I have some achievement glitches.

1. I played 6 KOTH(King of The Hill) games, but I still not get ((Higher Ground)) by now.

2. I reviewed all my stats from top to bottom but there're no Statistician

3.I invited 12 persons my I still not get People Person

1. Games played in /variants don't count for achievements. You have to play in live to get that.

2. That one has been broken since the site updated the stats pages a while back.

3. Did you invite under Connect > Friends > Invite Friends? 

1.Oh Ok  2. Oh Ok  3. Yes I did

Did you invite by filling in the e-mail?

Same thing with me, I invited 10 people but no achievement

It's possible it doesn't unlock until the 11th invite

guys you have to invite friends who don't already have a chess.com account, or you could just type in random letters followed by @gmail.com 10 times

i managed to get the achievement with my friends who already had chess.com

all i told them to do was click on the email link

i unfriended them

they refriended me through the link

i did that 10 times, until i realised just sending 11 different invites will do the trick and theres no need for them to click the email
