Glitched achievements--Anyone else?

[kiskit]

I finally unlocked the Pacifist achievement last night. I saw the "Achievement Unlocked" message. I got 55 cargo unloaded. I was online & everything was ok or so I thought. I checked my Gamerscore while still on my WP7 & despite the game itself saying it was unlocked, it didn't register as unlocked on my gamertag. Then I went onto XBL on my Xbox console. The achievement has not registered yet even several hours later. Very disappointed since this cheevo took a lot of time to unlock. Plus I only would've needed 1 more cheev to 100% it.

Has anyone else experienced glitches with the achievements in this game? Anyway, I just wanted to alert others to this potential problem...

Update: I deleted & reinstalled Harbor Master from my WP7. Luckily, I was able to better my ealier score of 55 with 63! More importantly the achievement unlocked this time. Only took me less than an extra hour of game-playing time to get this achievement to "unlock" again!
So, an fyi should this happen to others...try re-installing! Since then I had 1 other game that a cheev failed to unlock on my GS despite getting it in the game's list of cheevs on WP7.
