Sprint 21h 10/9/15 1 day race bug

[High Flyer]

So I went for the sprint and started my train with 4 riders, as I went to 3 riders at 350 or 300m something weird happened with my train as, if you can check for yourself, i didnt put my scurrent sprinter to follow anyone yet he followed a different sprint train.

As i see it you sprinted left. Then your train was forced into another lane where you got trapped because left was no room.

But then why did i follow the long train instead of sprinting while following noone

*Also, there was a large gap which my sprinters could have gone into/ overtaken the lone dropped rider.

**Also, how can a tired sprinter with less sprint skill stop me from overtaking him with a fresher better sprinter.

***Also, I noticed that my train fell back, caught up fell back, caught up about 5 times. Why was that?
