Hello and i just made a cool little walkcycle with sintel light and when the animation is looping i get a weird problem… On like one frame her leg like goes to another pose.
Can someone please fix this and probably clean it up a bit 
i might be a expert on modeling but a total noob on animations XD
here is a blendfile:

sorry it was to big for an attachment
Often I put the the start and the end when the start is the end . Get it? the start pose is your end pose no need to make it 2 times. maybe you did that.
oh thanks i got it now 
really thanks
