On the episode 'The great crystal caper' Ziggy drives voer sportacus' back, making him lose the crystal...

on another episode, (sorry i cant remember which one) Ziggy drives over sportacus again, when Sportacus gets up, we see the black gap on his chestplate, showing his crystal is missing, but next second, he has it back again when he talks to Ziggy.

Obviously they have just used scenes from the old episode, but surely they could have re shot the bit where sportacus gets up so he has the crystal? it costs roughly $15 000 per episode, so it wouldnt have hurt them to re shoot that little bit would it?
