So, I have one mod that changes recipe for logistic system and it's missing a necessary science pack technology.

I'm not sure if Tech Tree Trimmer should dynamically work with all mod if not already this is maybe a good addition feature.

It's supposed to work dynamically with all mods, though I'm pretty sure I never got around to adding one final step that guarantees it.
Currently the mod is assuming that all science pack recipes share the same internal name as the item, and it that's not the case, it will skip that pack.
I'll take a look and see if that's the issue, and if not then it's something else I have to fix :P

thank you for quick and detail response.
this mod sound like it should have been in vanilla feature. really appreciate your attention to small details like this

As it turns out, that mod was changing the tech tree after my mod already ran, so it wasn't getting processed.
A simple load order change fixed it in version 0.0.7

very fast O_O ! thank you!
