In the editor, the left MIF is connected to all of the standing fizzlers and the right MIF is connected to all of the reclined fizzlers:

However, in-game only one of the fizzlers will actually appear, seemingly chosen at random.

The expected behavior is that all of the connected fizzlers should be converted to MIFs (or whatever fizzler type is connected). If this would be impossible/difficult, then the rest should just appear as normal fizzlers instead of being missing.
