Stuck in the dungeon after "The raised sword"

I have completed the “The raised sword” level but the next one “Haunted Kaithmaze” is still locked, I can’t go on, what happened ?

Thx,

How about now? I have just recalculated the achievements.

If it’s still not working, try this URL: http://codecombat.com/play?next=haunted-kithmaze
