i should get this achievemnt:

But i didnt! i saved the replay xD here it is

Some of the ingame achievements don't work, we're aware of this it will be fixed, at some point.

True that, there are some coding errors with this one, so that's the reason you didnt get it in the first place.

so, will i get it?
and whi someone put the + before the thread name?

No, you wont get it until it's fixed.

The + in front of the thread means the question was answered.

SlipAnc: I think what he means is when the achievement is fixed if it will be rewarded to him, or if he will have to do it again when the time comes.

If this is the case, I would think you will have to do it again.

I'm not sure, but most probably yes.
