Resident evil 3 achievement wont unlock

I was told to do the same thing. I have four achievements that are 100% but have not unlocked. 3 of the achievements are from Resident Evil 6 and 1 is from The Division.

It is possible that there is a bug within the game. I had a similar issue with Bleeding Edge recently, where the last achievement that I needed wasn’t popping. It eventually popped about a week later when I started up the game again. You could try reaching
out to the developers and see if there is a report a bug feature anywhere in the game and explain your situation there, as it could be a game issue.

First congratulations on getting all of the Charlie dolls. That is a secret and rare one, 2nd rarest from what I can tell.

Check TrueAchievements to see if it has registered there. That will give some insight into whether the achievement has been acknowledged at all. If not then it is like my colleague said, an issue with Capcom and needs to be solved with them.

My only thought my be the order and therefore the trigger for the achievement. I would hate to see you have to start over but that may be it. Note to those that have not tried, the following are spoilers so don't click if you don't want to be spoiled!

I find that using TrueAchievements gives me a second view of what the XboxLive server has. So if the achievement is not triggered by the game, then there is no way that Xbox or TA will be able to report it. Just as a note, I have had this trouble also and
found that doing something (sometimes switching between console and PC) to get my account to re-sync at the game level fixed the problem.

Good luck and let us know the outcome.

Hmm it doesn't seem like it would be an issue with Live if it's been that long. It stinks to have to repeat stuff but you might have to try again.
