Guild Wars 2

Just thought i would ask about this.. I just finished up completing world 1 zone 3 on tribulation, and after defeating the frog king, i didn’t get the achievement for completing the zone. I thought that I may get it when the time runs out and transports me to the bonus round with the cart, but I completed that and still no achievement. The kicker though, is that I have the token for completing zone 3.

Is this a known problem, or did i just done goof somewhere along the road?

Same issue here, and i have all the King Toad Z-3
