There probably isn't a way to fix this "issue", but when the turrets upgrade they delete all the ammo that's loaded. Otherwise awesome mod!

Actually there was, and I also added support for modded turrets and a user controllable kills to promote.

does it preserve item slot ghosts?

yeah and you forgot to set the raise_built flag or it will be incompatible with turret shields or uniturret for example

newTurret = turretSurface.create_entity{
name=turret.name, position=turretPosition, 
force = turretForce, 
direction=turretDirection, 
quality=turret.quality.next,
raise_built=true,

}

Would this fix it?

yeah
