Bug 1:
You cannot set them to autofire... You can click on the checkbox but once you close it it is removed...
Bug 2:
You can only build 4 laser batteries. When you build laser batteries each of the one you build gives you one slot... Now for each one you destroy one of those slots are removed (with the weapon attached no less - I do not quite like this). Fine so far. Now if you rebuild the laser defenses AND complete them using "debug_buildingfinished" you end up not gaining the additional slots... If you let them complete regularly... You gain the slots if you let them finish normally... Not sure if this happens with missile batteries.
