I recently tried porting S1's motobug to S2. It worked, except the moto bug didn't interact with the floor properly and if you destroyed it then all moto bugs in the level would vanish. How does the game know which moto bugs have been destroyed and which haven't? Learning this would be the key to fixing the second bug. Has anyone else tried porting objects (not including S2B<->S2) and what were the results?
