This has been brought up before, but I've not seen it addressed by the developers on forums or in a change log.
Well, no matter how many times it has been discussed, and no matter how many people explain what the intended difference is, and over the course of regular play since the hour the game was released...... I still can't get Sentry and Guard to work differently than one another. Worse, neither works the way I want.
They both wake up the ship as soon as another ship is in its line of site, even if it's a micro-freighter, and often if it's not hostile. I desperatly want a way to tell a ship to sit there forever unless I click on it no matter what happens ever for the rest of time.
I am sick of putting my sensor arrays back to sleep every single turn. It's very frustrating when it's just one ship it keeps happening to. When it's several it is a regular nightmare and I have simply disbanded sensor arrays and random ships to save the hassle. I have also quit sending freigthers to alien planets before I research trade route increasing techs. I'd rather not have to deal with the annoyance of my trade ships waking up every single turn than get the added in-game benefit of trade routes starting the exact turn they are able to.
Please, Stardock. Please give us a, "Shut up and Never Bother Me Again" command for our ships.
