from the challenge board

I can see the RC for eps 5 is build it up, break it down
IC for 5 is eps Cat and mouse

RC for eps 6 Stones throw
IC for eps 6 under the stars

and eps 7 will be double boot with only one challenge "the gauntlet"



so i guess now they postpone the "build it up, break it down" till eps 6.

and cat and mouse become RC and Stones throw becomes IC.
