Hey I'm a few days into a Platformer run, and for some added flavor I also have the mod Modular Turrets installed. Modular Turrets adds several more gun turret variants using various ammo types, and while most of them are still usable, their Scattergun Turrets (which use Shotgun Ammo) are not usable because of the removed relevant Military techs.
Can this be a configuration option, to re-enable the removed Military techs? (Military 1/3/4, the ones that unlock Shotgun shells and Grenades)
Also, on a related/unrelated note, An Oversight:
Tesla Turrets are still available in the tech tree, but cannot be crafted as their recipe requires Tesla Guns, which have had their recipe removed. (not that Tesla Turrets would be very useful in space anyway since all asteroids are immune to Electric damage; although I suppose they could still be useful for Biter or Pentapod containment.)
