I have wait a long time, this achievements get fixed so i can continue playing this game, but no answer, i just sent a ticket to steam, and they say to me it was a developers fault, about like 6 weeks i send a mail to xseeds support, and this is what i wrote them, and the answer..
Do you read steam forums; there's a problem with YS Origins; The Global % of Achievements, isn't updating, i have an achievement that says 0% has it, but a lot of people have it; i send a ticket to steam, and they answer me that i have to contact the developers...
thanks for the answer
According to our programmer, this issue is due to a cloud synce issue on Steam's side, so there is no way for us to address it ourselves.
From what I'm being told, I believe that if you continue to look at other games' forums then you will see that the issue is not unique to Ys Origin.

this is the mail of support; firstname.lastname@example.org
