Open Modular Turrets

Added

• The potato cannon turret can now also fire poisonous potatoes

Fixed

• Projectile turrets now lead the target with the real flight time (air drag) and raise the aim by the projectile drop, so slow projectiles no longer hit below the target
• Projectile turrets aim at the target's eyes instead of its body when a ledge hides the body, so shots no longer hit the block in front of it
• Potato cannon and disposable turret projectiles are now visible right at the turret instead of a few blocks away
• Potato cannon and disposable turret projectiles show a potato or cobblestone when fired without ammo (creative upgrade)

Changed

• BREAKING: Renamed Relativistic Turret to Slowing Turret internally (lang files with be changed later)
  • This will cause all existing relativistic turrets to disappear
• The inaccuracy of the turrets was increased due to the targeting fixes which made turrets way too accurate
