Yet another series of questions

[Phlagm]

Followup to part 1. The only way I can think of to get the fleet to move to a specific location is if I make it a homeworld of some race that doesn't matter (say damocles). And then set the fleet to "attack damocles"

I'm about to try this with a regular fleet, as the hyerdrive fleet never showed up (but that may be due to other things). But there's still a problem I've encountered, if I set the planet to damocles's homeworld, it has three free items (which is not what I want).

Also, is there a way to check if a race exists before making a quest involving them? I would like to make a Tan Ru main quest, but I need their homeworld to be there, or else I need to make it. Is there a way to check to see if that race has a homeworld present already? If not, I can make a workaround for this particular problem.

And one more question, is there a way to trigger a quest upon a return exploration of a same planet? Will "explore" go off a second time? I'm thinking that it won't and that's why I cant get one of my quests to evaluate.
