Why do my fleets always head home?

[eroyce]

Hmmmm.

I've been playing single player for a little while and there's one thing I just cannot understand. Every single turn all of my fleets try to head home.

Is this something from an Intelligence action? Why isn't there anything in the log then? Why does it still happen when I've got over 800k Intelligence points?

Frankly I like SEIV. The user interface is absolute garbage not worthy of further comment. The gameplay is ok. But this nonsense with the fleets having their orders changed constantly is really very irritating. If it is due to an Intelligence action by an enemy then I'd also like to know why it's not in the log at any point?

And I am not using any Ministers at all, at any level.

Thanks in advance!
