IMHO, nothing should auto-repeat without there being an option to turn it off (and preferably have it off by default).

It would probably be nice to just have more than one Treasure Hunt (and all other Missions) queueable.

That way, you can repeat it as many times as you want, and when the queue is finished, it pops back up as Idle.

If you can have multiple instances of a Mission in a shipyard queue, this fixes the problem without having to worry about an auto-repeat feature (and it's warts).  Queue up 5 Treasure Hunts, and maybe in 40-60 turns you have to do it again.

Problem solved.

Agree with this. If Stardock choose to make something repeatable with one mouseclick, it should default as nonrepeatable until that mouseclick is made.

Maybe this could be a game setup option - making Missions, as you get them through Research, autorepeat or not. But how long do we want the game setup to take? There's plenty of options to think about as things stand...Do we really want things to get to the point where it takes twenty minutes to set up your next Galactic Civilizations III game?!
