I have been having problems lately with this happening to me. It has been fine for the past several months, but last week I simply could not getit to lineup and the best I could do with my 82nd is a 280 on the 5 spot.

I fixed it by putting twists into the string or taking them out. Once I got it as close as possible that way, I manhandled the d-loop into positioin. Now it is fine.
