Didn't receive Forgotten Battles' achievement

[Black Power Soul]

Hi there! As the title says, i've completed all Forgotten Battles' scenarios, but i didn't win the achievement for that. I "lost" almost 57h to beat all of them and now i don't know what to do. I'm very disappointed to take 4, 5 or 7 hours to win those games and even more now without the reward! In other words, i wouldn't like to play them all over again to find whence the issue is. I thaught it was for Kurikara, cause when i won first time i didn't receive any point for win a game with the japaneses and any for defeating them. Now i've just played it again on "easy" and i got all those points, but not the FB achievmnt. My last try will be in York's scenario.
Two questions:
I won every scenario on hard mode. If i beat York, for ex., on easy, it would count to obtain the achievement?
I think i have all scenarios save games on a "half-win" conditions (i last saved only a few minutes before i won the challenge). Could be possible i send these to the person responsible and then he/she can realize i deserve the achievement? Haha

Ah, and i appreciate "AoF_1302" answers and care. Thank you, fella.

The developers can't give you any achievement, even if you deserve it, so thats not an option.

My question: Are you sure you completed all of them? Because sometimes a game bug load a wrong mission(another mission from another campaign).

You can try 3 things:
1. Try to complete any of them again on standard difficutly.
2. Complete all of them again with i r winner, and then complete one of them without cheats.
3. Make a new profile in the game menu, complete all battles again with i r winner. Complete one of them without cheats.

I'm sure one of them will work.

Steam handle teh Acheivements.. so good luck getting them to fix it for you :(

Try loading those saves and carefully make sure you don't overwrite any. Or you could actually play them all again, using different tactics. All good fun.

I'm surprised that onyl .27% have won it.. so it may be a bug. I know I missed out on a couple of Civ V acheivements through bugs.

I played all the scenarios through twice, some good ones I played 3 times. The different tactics needed in some really make the game worth it.

Yes, i remember some time i tried to launch a mission and the game started another one. But i always restarted the game when it did happen. And yes, i beated all of them. I will try option number 2. It would take several hours to win all missions again, and i don't have patience enough to play more than 4h per game. My guess the bug was on York or Langshang Jiang. Thanks for the answers and hints.

Played York again, but now on standard. Won in the same way as the other time (on hard), constructing a wonder in Northumbria. And now i've won the achievement, finally! Maybe the other time the connection had fallen during the game, i suppose. What a relieved i am, free!
