missing achievements

Hi, after many games of trying to win a game with checkmate by a pawn, I finally managed it, only to find that I still don’t have the Killer Pawn achievement. All the other ‘Killer’ achievements worked the first time I managed them.

I am also missing achievements for drills, I’ve probably done ~20 but I still haven’t even got the achievement for ‘attempt 1 drill’ (whatever it’s called…)

Seems I’ve done 11 drills, but should still have ‘train your brain’ and ‘brains of steel’ on top of ‘killer pawn’
