I may be missing something here, as I have not read all post in the last week or so, but am I right in saying the Thargoid bases the Eagle Eye facilities were looking at have gone quiet, and therefore there is no way to see where the Thargoids are going to hit next? And that you are trying to work it out via other methods?
It is not too much of a leap to think that the Thargoids worked out there data was being taken, so they stopped using those bases. Surely then you would need to look at other bases to find which ones are now providing the target information?
EG Eagle Eye did it's job OOC: it showed the mechanic for finding out the systems that would be attacked. It made it easy be giving you the first Thargoid location to get that info for free. Now that the mechanic is established they have taken away getting those locations for free. Now you need to find the active ones yourself to get the targeting info.
That is how I read it.
