I seem to have lost 20 rep with no record as to why in the reputation log?
Some days ago I was on 917 rep. The following screenshot showing 912 rep is from Google Cache dated 22 Dec 2013. Since this date I received +5 (on 22 Jan) for an upvoted question. I also rec'd +2 today for accepting an answer (so total should have been 919).
However, according to the reputation log the only down-rep reported is a -5 on 8 Dec 2013 (before the above screenshot) when a "user was removed".
So where has this 20 (919 - 899) rep gone?
I thought that maybe a question was migrated, but shouldn't this be reported in the rep log? And I don't see any change in my rep on the other sites in respect to this.
