[h1]UPDATE: There may still be some issues with this achievement unlocking. A support ticket has been raised with Valve. I'll post any updates here.[/h1] [i]Original post follows...[/i] The 'Paid in Full' achievement has now been fixed. This achievement was not unlocking when you hit the 50,000 point requirement. The fix has been published in the Steamworks back-end, therefore no update is required to the game itself. Apologies to the 2 people affected by this. The rest of you need to step up your game!
