There was a thread going about this yesterday, yes it is always scary when a model is fishing for something that really isn't there yet, after all, that's how it all begins.
When you get 2 models it definately raises eyebrows, altho the MM5 is usually tossed.
Oh and as far as nothing on the new run, that happens all the time with developing or "to be" developed systems. It'll show in one run and not the next...then it'll show up again.
The name of the game here is consistency
