Sorry for bumping this up:
Is there any one who can help me? I searched now for over 9 hours and can’t find the Problem.
I made a blank Project that uses my steam app id. And there i can unlock the achievements. But not in my Project. I looked into my defaultengine.ini, changed everything to empty, uses only the Minimum Installation and so on.
The overlay works. But i can’t unlock the achievements.
One Thing that i found is: If i package the game in 4.15 the achievement (one over a key) works only in the main menu, but i don’t have to click any button or something. If i click first on the menu and try to use the key, nothing happens.
But every Level uses the same Settings (game mode, Player, etc.).
What uses the standalone window to use steam what my game not have. And, two or three weeks ago, all worked just fine. Without any Problem.
