Howdy,
So I did a bit of file tweaking on a separate install to determine how I would like to compose my fleet makeups for battle. I edited all the build times and costs of all TEC ships to a numeric value of 1. I also changed the research times and costs to a value of 1.
After doing so, and launching the game, I had these huge fleets of pirate ships showing up at my homeworld after 10-15 minutes of play. ~50-80 ships in each wave. I made sure to NOT touch any of the pirate entity files.
What gives? Do the pirates spawn at a rate and strength proportionate to the size and strength of the fleets I am building?
