My characters head will not connect to its neck at all it just keeps floating around, i've got the crown symbols on the body and head tabs switched off so they're not independent i'm not sure what else to do.
Could you include a screenshot of the rigging hierarchy? Very strange its floating away if independence is turned off! You could try holding ALT and pressing the refresh button in bottom right corner of scene window (two arrows in a circle icon). That flushes some internal caches.
The other thing to try is to click on the mesh icon (bottom left corner of scene window) to see what the mesh is of different layers.
The other one is to check the “Head Postiion Streight” property of the Face behavior. Try setting it to 0%. Does that help? If so you might like a value of say 10%. The default of 100% is too much for me.
