I just made the "Blast mastery" achievement, causing 10.000 damage with energy weapons.
Now I got something strange in my steam going on.

It says on most recent achievement: Blast Mastery.
If I now go to the personal achievement page its not yet achievet.
What did I do wrong and how I still can make it?
(Its not a game bug, so i made a seperate topic for it)
