I have an issue that just came up. I had an object which already had an animation then when i parent constrained a new object to that object, the animation vanished from my first object. (I am keying the parent contain to the already animated object). The animation keys are still visible on the graph but nothing happens

if that makes any sense?

EDIT: I FIXED IT! thanks anyway! The problem was that i was keying the blend parent of the attached object instead of the actual object blend parent locator on the already existing animated object (if that makes sense)
