By the point you can make a corvette cost over 200 minerals, corvettes are cheap distractions more than anything. I don't feel like a rise in cost would really be worth the effort, especially if you then continued to use cheaper corvettes. I'm also guessing that said rally points are the vanilla ones which can be set to send ships to an existing fleet or object.

Definitely using this mod, of course. I've always wanted something to automatically build swarms of corvettes. This is perfect for that!

You can set them for planets or fleets.

I am using Mamalian ships.

Which race are you? I thought I added model entries for all of them, but might have missed some

What rally point would they go to?
I could pick a random planet you own in the system, or just a random planet, but I'm not sure there would be much benefit to that
Can you set a rally point for newly built ships on a planet?

I have it working, but the station has no model. It just shows a translucent box. The ships also go idle when built, rather than moving to a rally point.

The mod list shouldn't have anything to do with save games - it is save game compatible although you might have some wierd things happen if you build the station, save your game, then remove the mod. They just released a new minor version, which means I had to increase the mod number from .1 to .2 for the game not to complain about it

I have not yet seen this mod appear in my mod list. It might not be save game compatible.

Yes - I think I might try and make the cost scale with the turn number or tech level

In the late game, I can design a corvette that costs over 200 minerals.

Sure, I just made this one as a concept but could add in the rest of the ship types
Probably the biggest issue is that I can't get the actual cost of the design, so I've tried to slightly over-cost the production to compensate for the automation (and the ability to build ships anywhere you can build a military station)

How about stations to build other kinds of ships? This would be helpful late in the early game. Late in the mid-game, I need to crank out battleships.
