Answer 1

Is this a known glitch? http://i.imgur.com/JJmnd8t.png

Spread dust with an up heavy and climb that wall, but it doesn't get cleaned.

Answer 2

I got it in testing, which is why the dust isn't placed as high as it could be. If you do this then try to upheavy again before you climb the wall.

Answer 3

I just upheavy the dust on that part instinctively.  There's no real benefit to climbing the wall, since you can line yourself up anyways.

Answer 4

Yeah I changed to downheavy after I did it a couple times. Just thought it was weird

Answer 5

Man all these of yours for the race are incredibly cool
