I installed the game and played it for a while, it had no problem until I've got an ending and didn't get the achievement. I tried it again, again. After that I tried to get the other achievements and they didn't worked out as well. I unistalled and reinstalled the game. I tried to check the local files to make sure that I had no problem with it. I tried on another device to get the achievements. Didn't work out. But surely it isn't about me because I've been getting another achievements on other games after this happened. Any help or anyone knows why is it happening?
