Guild Wars 2

I have done all the wintersday achievements (except one), but on the upper part of achievement panel still says 15/20 completed. Thus I haven’t received at least couple of rewards (mayhem and bells) from completing those achievements. I think I have received achievement points though, but it is just missing the point in the bar (15/20). I want to complete all so this problem might make loose my reward from whole meta completion.

You’re not supposed to get 100% completion from completing all of the Christmas achievements. You also have to complete some of the infinitely completable chievs and do the daily Christmas chievs. You can find these under your daily tab and they will have a the same picture next to them as any of Christmas chiev.
