Hey Adrian.. Is it possible that you have two or more upvectors operating on the bone?
Grab the thigh or bicep bone and check out its properties in the explorer, or by clicking on the 'selection' button at screen right..
Do you see more than one upvector operator active?
The other thing you should check is whether or not the resolution plane of the thigh or bicep is set to default or UpVector... naturally, it should be set to upvector...
Did you remove the constraints on the bone via constraint > remove constraint, or did you just try to write over the old constraint?
Sometimes I've found that removing the upvector constraint does not reset the resolution plane to default, rather it stays set to upvector even though the chain clearly does not have one.. so sometimes you mnay have to manually set the resolution plane to default, and then re-attach the upvector
let us know what the solution was
