Inserting keyframe makes armature and mesh jump to the other end of the screen.

So i’m animating a character walking across the screen. I’ve made a walk cycle and all of the key frames are inserted along the time line for the walk cycle. But when I try to insert a LOCROTSCALE keyframe the armature jumps across to another part of the screen and distorts in various ways. Anybody have any idea’s as to what could be the problem?

upload your .blend to pasteall so people can take a look at it, you will get a quicker response.

good luck
