When I check here, http://assassinsnetwork.uk.ubi.com/pc/acb/achievements It says that all achievements from "TECHNICAL DIFFICULTIES" to WELCOME TO THE BROTHERHOOD" are locked. But I already unlocked them. During gameplay I kept checking and it was all right. But now they got locked again. The others from "CAPTURE THE FLAG" to "EASY COME, EASY GO" are ok. I already completed 100% of the game, including DLC and all adiitonal memories. Plus, when I check the achievements inside the game "OPTIONS-STATS-ACHIEVEMENTS" it says that everything is complete. I already begun a new game but it doesn't give me achievements complete anymore. Is anyone facing the same situation? Is that a known glitch or what? Thank you!
I have same problem.
But what is more worse, I already uninstalled game for the moment, when found this. And when installed game today, all my achievements and statistics were zeroized, both on ACnetwork, and in-game
Even if the post is quite old, I had the same issue this evening.
I completed all the achievements, I was missing only the 16 subject one (the glihps) and all the achievements (except it) were correctly syncronized on the website.
After completing it, now I only have 22 unlocked achievements, even if in game I have 100% and the summary on the assassinscreed newtork itself says I completed the game at 100%.
Additionally, in UPlay I have the action to take the eden apple done, but the achievement not... just this can prove that there's some glitch.
Sad, but noone of support team cares of these issues. More than 6 months have passed from my previous post in this topic, but there are no changes in Assassins Network. Tickets to support do not help too...
