This didn't pop up for me after modular weapons

Thank you immensely modding friend! My particular combination of many mods seem to generate a "mod bug" that would prevent this incredibly crucial research from appearing until late game, or practically not at all. OR sometimes I'd get it second research refresh! Incredibly annoying as it would often not appear in really sold excellent starts/campaigns. You fixed all that...thank you...again.

Just finished a campaign with about 280 mods, this one included, and had no major issues! Thanks for putting this up.

@TeslaRage good catch, ill check how the CA spawns the breakthroughs

@Hotl3looded Just discovered that you need to disable the ones attainable from covert actions. Screenshot here: https://imgur.com/Wt0NhyJ
The one for weapon upgrade appeared earlier on for me but I didnt take a screenshot.

@Charchu ok uploaded the fix and updated the mod description.

@Charchu I just checked the research projects from the original mod and nothing happens if you do the vanilla Breakthroughs. So the new Breakthrough would stay in the research list until you decide to research it (redundant).

I could add a fix for people who have already researched the vanilla Breakthroughs in their game.. it would disable the new Breakthroughs ONLY if the vanilla Breakthroughs are already researched.

so what happens if you already have one of the vanilla breakthroughs active?

Thanks for this: little bit of cleanup is nice.
