In Ridge Fault for example i could not open the Chest inside the Water. The last switch is always red. No "Key" is working.
And in Ridge Fault there is a secret way right after the entrance, leading around the abyss that can not be reached.
Is there something special inside, even a Rubie ?
EDIT : just a few MINUTES after this post, i got a diamond - unbeliveable Murphy
But i can still not open the chest in Ridge Fault
