Peg won't stay in place.

Hello, does anyone know the reason why my pegs are going back to their default position when I switch layers and what the best fix or easiest way to rig a character is?

No one has answered your question yet, that must be frustrating! More information might be useful - what are you doing to move your pegs? What level of Harmony are you using?
If you are moving the peg’s pivot in the animation mode, with the translate tool active, you are only temporarily moving it. To permanently move the pivot, you need to be in rotate mode. Hope that helps
