Animation Mode ~ Constraints Order

Hello!

I’m working on cleaning up a mocap FBX character animation that uses a separate SKM prop. Constraints work great to keep the prop on the character, however the stack order I’ve established for my constraints reorders incorrectly every time I save my level sequence. It’s easy enough to order them each time but I’d love to know if this is a bug, or if there is a hidden influence to their order that I am not aware of. Thanks for any insight!
