alright so i was trying to do all the mara sara achievements and the last 1 i had was the zero hour one where you can not lose any buildings or salvage on normal difficulty. I did not lose any structures or salvaged anything and i beat the stage and did not get the achievement! another issue is that sometimes while playing the game will d/c from battle net and i won't earn any achievements because of this. my question is why did i not receive credit for the zero hour achievement and is it possible to load my last save and finish the mission again to gain the achievement?
How sure are you that you didn't lose a structure? On that mission there are several waves of mutalisks that come from undefended angles into your base, they may have destroyed a missle turret or a supply depot while you weren't looking.
I'm going to assume the OP checked the summary after the mission. @OP Yeah, you could continue from the save.
i set out personally to take care of this mission i know i did not lose a single turret because i have played this mission 4 times before and know multalisks come from the middle and sides on the upper level which i had guarded with more turrets and bunkers with a 2 scv on stand by
