i don't need an explanation

because what luke saw was just a meteor

star wars movies do not jump around in time like that

i'm just saying the fact that the probe droid doesn't approach luke and the wampa adds to the case of it not being just a few hundred yards away at that time - and it is conspicuously absent through the whole of the rescue of luke and han. if it had been around it would have recorded the transmissions broadcast from zev and the other rogues (commander skywalker do you copy? captain solo do you copy?) and transmitted them to the empire rather than just an image of a power generator. it didn't do it coz it wasn't in that area at the time.

what are the chances of it landing within spitting distance of vaders number one target when it would have had a vast (maybe planetwide)area to cover
