When I'm trying to research Beam Fire Controls, they're showing up in different areas. Beam Fire Control R96-TS9000 is an Energy Weapons item, while Beam Fire Control R192-TS9000 is a Sensors and Control Systems item. I haven't researched them yet, but the costs seem correct for both.
Also, I'm seeing weird things with turret prototypes. The first one I tried to make wouldn't show up in either the prototype list or the research options list. The second one I tried to make (with the same name and stats) I clicked Prototype, and it shows up in the component options list as though it's already researched. And I don't have Spacemaster on, so I don't have an Instant button that I could have clicked.
[Possibly intended] When I set a ship to survey as its primary standing order and refuel as its secondary, when it runs out of things to survey and goes home to refuel, it sends an "Orders Assigned" event every single tick, even after it arrives home. Changing the secondary standing order to No Orders fixes this.
This is intended. Leave secondary order empty and use Conditional order for refueling instead.
I have that on too. I used Refuel as a stand-in for "head back to a base and wait there if you can't survey any more".
