Hi Harris – it looks like you figured things out.
Looks like the motion paths can now show before and after colours as default rather than the subtle blue colour for the ‘before’. The devs would have to chose either the past or future colour to override when they overlap. I would probably favour the past as well, as where the object has come from is more important imo as that is what the audience has already seen.
The Bone colour groups have been in there for a while. You can disable them here
