How has no more trigger techs been incorporated into the patchset? I couldnt find any reference to it or it's code in the files

It's here.

Its job is to prepare the base tech tree for IR3 to work on, but leave Space Age triggers (and other mods' triggers) alone. I expect you're wondering how the mod is going to work with the real NMTT, which I'm afraid I haven't tested.

Knowing how NMTT works, nothing should happen. I assume you just borrowed the code instead of having to invent it yourself?

Yes. The mod is MIT licensed so I'm assuming that I have permission to use it, but if I don't then I'll rewrite it.

The comment at the head of the file explains why I copied it instead of making a dependency: I need it to run in the data.lua stage before IR3 starts building the tech tree, instead of at data-final-fixes.

Sounds good. You might be better off doing it manually, since other mods can load before this one and it'll throw off what is managed by NMTT.

Do you mind linking to the mod/git page in the file?

You mean just putting a URL in the comments? I'll put it there in the next commit.

I've changed your code to operate on a whitelist of only base techs, and if any third-party mods want to be sneaky and insert their techs in the way, then they probably aren't compatible with the Patchset to begin with.

Seems like you've got it covered then. Good luck!
