Problem details: The bug happens when you snap a green line and a red line in the same offset. The green line looks like it's before the red line and it doesn't work as it should. That's weird since some maps can start with a slider and you want to modify that slider velocity.

^- This pic is just as how does it look, I can't adjust or change length of the slider.
