Country upload stats suddenly decreased


I check from time to time my upload stats in the country statistics of the old website page ( This week I noticed that my stats decreased by around 50 K without notice (I used to have around 120K and now I am back at 75K pictures). I am curious about this change because the picture coverage in the map seems to be same (no large number of sequences has been removed) and my upload stats in the profile show the correct value.

What is it?
