I have to make a deer in a forest by next Thursday, and I’m having trouble rigging my deer. I put all this time into setting up IK and stuff, then sometimes if I do something weird, or even when I Save the scene, and Reopen it, This happens.

I don’t know how to fix it. I have Re done this so many times, because I screw one thing up. then When I’m happy with it, I save it. Then when I open up the saved Scene it gets all screwed up!
Does anyone know what’s going on?
