Posted this on the official SC2 forums, but have yet to find a fix or workaround.
I completed all mission objectives in the mission Welcome to the Jungle (screenshot proof: http://yfrog.com/59screenshot2010073100092j ) without using cheat codes, but was not awarded the achievement.
I tried reloading the most recent save file, completed the mission again, and the game still failed to award the achievement. I tried loading the most recent save a second time (my third time completing the mission) and the game still refused to award the achievement.
I tried reconnecting to Battle.net and loading the save. Unfortunately, the achievement still didn't unlock.
But still good advice for others. It just didn't happen to work for me.
Thoughts?/bump
The game is not recognizing that I have completed the Welcome to the Jungle mission and that bug is now resulting in the game refusing to award the Liberty Completionist: Normal achievement. (Yes, I played on Normal the first time around so I could enjoy the story without having to retry missions.)

I have tried re-loading a save file from the nearly completed Welcome to the Jungle mission and re-completed the mission four (4) times now. I have verified each time that I was connected to Battle.net before completing the primary mission objectives.
Seeing how this bug (or type of bug) was not addressed in the first two patches, is anyone aware of a workaround?
