UE gets a pop-up, first on the right. That it has found the Academy.

But i did nothing. 

As you can see in the save, not one system of the Academy has been found by me.

At first I deleted the report, because i thought it was just how things went.

But in another game i play, this didn't happen.

So I undeleted the report.

What faction did you choose in the other game it didn't happen? I can confirm same bug when playing Nakalim in 1.5.10 at least.

I believe it was Umbral Choir. But only once. 

With the Vaulters the bug was there also.

With the Umbral Choir i just got a message that the Academy was found.
