This is kind of weird and I have no idea what I did to cause it.
My little lego man is now 3,330 verts and about 3,500 faces. While being a rather boring first model it has been very educational.
I have started rigging him now (thanks to Fligh % for help with the sharp joint problem) and have started on the arms.
Now I seem to have done something (I think it might be due to the weight painting) to muck up his arm. When I rotate the Upper Arm up the verticies at the point where the upper arm and lower arm join seems to get a little left behind.
The weight painting at that point is upper arm is RED turning to Green at the shoulder and the Lower Arm is GREEN.
I have fiddled about but have no idea what I did, I have also tried deleting the Vertice groups and remaking them but no luck.
What have I done and how can I fix it?
