Thank you for reporting this. I just want to let you know that I have properly documented and submitted this game behavior to our team for further investigation. At the moment, we cannot make any promises about a definite fix. Though please stay tuned on our official channels to make sure that you would not miss any update.
You literally have to let the game load and WAIT 5+ minutes for the game to sync with your server. Sit in the main menu/or character selection menu for over 5 minutes. If you are over 75ms ping rate, it will not load achievements nor sync with the server. This is what happens when your “experts” have no clue on net coding.
Forgot to say I am on a Verizon 4G internet connection. I believe this also compounds syncing issues. I have never had anything ping below 59 MS. I can play Lord of the Rings Online/WoW with no issues however.
I’ve noticed this on and off since i started the game, but i think it has to do with steam/new world sync and not specifically one or the other. I noticed that when one is not working, the other is not either.
It re-appeared after the Medley update for me. Before that I had no problems after one of the previous patches.
I usually get it fixed by logging out and in, just as many tiimes until the achievements do appear. But this problem is as old as the game itself, they did fix it at some point (without knowing that they did I think), but with the summer update it resurfaced.
