I received an email from drifter397 this morning...
"It took me quite awhile to practice for it, but in the end it all payed off because I finished ParkourPro! Thanks for the extra challenge! Here's the screenshots."

Congratulations! Tatankore has already put the 128 Industrial Diamonds in your inventory as promised!
We were surprised someone managed it so quickly but at least everyone else who is trying knows it is definitely possible with enough practice!
