Okay this is a problem I've run into from time to time and never understood the logic behind it, so I'm asking here...

It seems to usually(always?) happen on characters that already have an existing rig with animation on it. The problem is that sometimes when I add a new bone to an existing rig, and then try to weigh the mesh to the new joint, the mesh will shoot off in an weird angle instead of staying put. Does anyone know what causes this? It's very frustrating. Thanks in advance

Maybe you are adding the bones outside frame 0(zero) which is the default "pose frame" for the Skin Modifier. The modifier will then readapt the mesh from frame 0 to its current configuration in whatever frame you are.

Double check the reference frame configured in Skin and the frame you're on.

Perhaps it's not it, but it worths as a record for the casual forum reader.
