I've tried taking this mission in Latos and Odia recently. Once or twice in Latos I've encoutered enemy bots, after that only a Hive observer and since then just nothing - no enemies at all. Is this normal? Could it be perhaps related to some Hive/Leviathan-related issues?

This never happened to me in UIT space.

Also is this mission supposed to give me anything as in the Mining Excursion missions? Or does it just go on forever? lol
