Achievement Points and Server Shutdown

I acquired 3 achievements (30pts) last night that aren't showing up on the armory now. I didn't logout before the server shutdown on July 06 and wondered if they're going to be recovered when the servers come back up.

There was a time around 2 years back that I came back into the game after a summer break and discovered that I was missing 120 achievement points from where I left off. Never got those recovered, and I'm not sure why I had to lose them.

Any info would be appreciated.
