Problems!

We've hit a block. All the characters are weighted and working fine. Only problem we're having is with EggMan and RobotMan. Egg man is almost fixed but there are still problems. When rotating the joints other parts of the model stick with them and get rotated too. This is a massive problem as we can't go onto the easy animation stage without sorting this problem out first. A lot of people in our class don't know what the problem is either- weight painting doesn't seem to be helping.
