Thanks for all the suggestions. As it turns out, I put the MAX_CONTACTS to too low a number. I put it up to 50 and now collision rarely goes wrong.

It does still mess up occasionally. I'll put it down to 'problems with opcode' that someone mentioned.

This must be what was happening

Sorry I wasn't being clear. I calculate the mass using DENSITY * dimension. Therefore big objects become very heavy. If I scale my dimensions by 100, the object will be 100^3 times heavier.

Thanks!
