Tomb Raider: Definitive Edition

I just got this without doing the tomb in coastal forest

Can confirm still bugged March 2023

Jogo totalmente bugado, não me deu essa conquista e também a de arualizar as armas o máximo..5000 fragmentos eu ja peguei muito mais que isso e nada de conquista. Fora também que ja devo ter incapacitado pelo menos 50 inimigos e nada de conquista..to fora

Just a heads up for anyone else, this did not pop for me when I completed the tombs. It also didn't say Done - Unlocking. It did end up popping two days later though.

For players who seem to have had this achievement not pop due to some strange glitch on Xbox, even though you might have 100% completion, there is a way to get it to pop. However it will be time consuming and annoying. The cause of the glitch is still unknown as of writing this , whether it is something to do with game servers not relaying player info properly or just the Xbox side having an issue. This glitch recently had happened to me and i tried desperately to find a solution to no avail, I did what worked for me with a previous glitched non poping achievement i had for this game (reach lvl 10 in multiplayer).
I am going to preface this solution as a last resort, and I advise that if you haven't gotten the rest of the achievements before hand, such as the multiplayer and other collectables, that you get them first and get them out of the way. What I ended up doing was deleting all my save data for both on my Xbox and the game servers that way I started from fresh and once I spedrun through the game to get to the last tomb I needed raiding it popped. The fresh start for some reason also refreshes whatever causes the glitch to begin with. It worked for two achievements that I was unable to pop even though I had done everything required so I would say it is a reliable tactic, but who knows if it always works. But I do strongly advise that this be your last achievement if you are going to attempt this and that you have expended all other possible solutions if any.
