When this mod is loaded alongside Space Exploration, it forces the research "combat rocketry" to require deep space science 3, effectively locking the basic rocket launcher and all research after it behind very late game tech. This doesn't completely softlock the game, as far as I can tell, but it does have a huge effect on it.
Thank you for making this awesome mod, by the way. The turrets look fantastic and feel well balanced, and it's clear that a lot of work and love was put into them all. I was very sorry when I saw that I had to disable it in my current game.
Thank you for your time.
