I do not know if this is a possibility but it appears that some satellite imagery providers have apparently been using software to filter out objects that are not structural in nature. This has been known to happen with major airports in which the imagery lacks both aircraft and ground support vehicular traffic but clearly shows the terminal buildings, roads, etc. I have also seen this in imagery of parking lots with no vehicles present but on dates in which there was surely traffic present. This has been known among airline enthusiasts for some time. Interestingly this type of imagery seems to come and go in some cases on Google Earth as there was a point at which no aircraft or vehicular traffic was present at Philadelphia International Airport (I believe that was the airport), which is pretty much impossible, only to have this traffic reappear sometime later. I'm assuming that this is being done digitally by either comparing layers of images or comparing several images taken within a short period of time.
I don't know if this would apply to the Blough not showing as being at Conneaut, but more than likely, as Mr. Link has posted, the imagery to which you are referring most likely dates to before the Blough arriving.
