You guys seem like the people to ask. Is there a bug, for some players, where the datapoints provide (is this another term for "drop") nothing? I've scanned at least 15 and got nothing at all, and my data storage does have space. There's a guy that did a YouTube video for finding MEFs and I asked him about it, and he said it's a known bug. I just can't find a definitive answer, and need to know so I can stop wasting so much time doing it.
Hmm. Known bug? Strange. Personally, I've never encountered anything similar and this it the first time I've heard about it - but I never searched for that kind of info.
Yes, once I've got a report from a commander (one of the contributors for the "statistic" page so he knows the subject) that in fact once he doesn't receive anything after a successful scan of the datapoints chain in one low-security settlement (and the datastorage was not full). So far this is the only one case known - all other were related to storage limits.
So I'll check bug reports... Hmmm - the only one I see so far is also due to storage.
So looks like this is pretty uncommon.
However, some questions:
What do you mean by scanning 15 datapoints? Only successful scan of
a chain of datapoints (minigame) - in a bigger-than-tiny settlement - will provide you with "data" materials. Scanning individual datapoints doesn't count and return nothing.
UPDATE:
Also, I was wrong about the only known issue - in fact there are no known issues, as that one I've described was related to the fact, that particular commader have received only one seed of data (and not two as that was supposed as minimum quantity up to that date)
