Ok, so I got this really great idea to expand on the whole "Arnorian technology" thing by creating some Arnorian-based weapons and defenses - three new weapons (Beam, MD, and Missle) and three new defenses (Shield, armor, and PD). I got all of the Beam and MD related techs to work just fine in-game, but for some reason, I can't get the missle related techs working to save my life!

The problem is that the final level of the missle techs are either separated from the main branch, or missing altogether. And even if they're on the research screen, they don't give you the missle techs even if you research them seperately. I'll put a copy of the tech's GC2Types and TechTree XML entries here, if that will help:

[DisplayName]Alzeron Missle Defense System[/DisplayName]
[Cost]10[/Cost]
[Description]Extraordinarily advanced missle defense system.[/Description]
[Details]With our advanced knowledge of Arnorian missle defense technology, we have designed a highly advanced missle defense system. The Alzeron Missle Defense System utilizes AI-controlled "smart" drones that use an electronic disruption system to short circuit missle guidance systems before they can lock on to our ships.[/Details]

[Description]Arnorian-based missle weapon of terrifying power.[/Description]
[Details]Through extensive research of Arnorian missle weapon theory, our scientists have learned how to use gravitron containment fields to "bottle" dark matter into a guided delivery system that creates a miniaturized black hole on contact with the enemy.The DMAD (Dark Matter Assisted Delivery) System is technically classified as a missle weapon because it utilizes a computer assisted delivery system and the damage it inflicts is not kinetic, like a mass driver. It is a frighteningly powerful weapon and must be used with extraordinary care.[/Details]

And before you ask, yes I do realize that those attack and defense values are a wee tad on the high side.  If I ever decide to release this mod on the Library, I'll balance it out but until then, it's for my own private use, mmmkay?

Anywho, If any of you Galciv2 modding geniuses can help me resolve my current dillema, then I'd dearly love to hear from you, because I'm just about ready to start ripping out my own hair over this!
