Hi there, thanks for the condolences. Basically my own fault. :-/ Maybe I shouldn't be trusted with the buggers. Thanks for the offer of sharing a UA, though.
The only thing I have thought of so far was putting them somewhere and see whether they change their song. I remember that Jacques said "They sing to you" in one of his messages. But so far I am having a really hard time to really decipher the sounds they are making. Somehow in my sound programs it never looks as clean and clear-cut as in the posts of the people who did it originally.

So so far I could not really say if they do spell out anything else than our ships.
The only ideas I had so far was o try and let them scan the nav beacon instead of our ships, but as I said, that resulted in a loss of the UA. Somehow I do not think that "putting a UA next to commodity X" will be a worthwhile set of tests, but you never know. Releasing them in Jacques station was another idea -- but that would almost certainly also result in a loss.
Cheers, CMDR Heisenberg6626
