You need a lvl-6+ scientist in physics to get the delta reactor (you also need particles specialty and/or something else) after completing the science convention.

same problem here

got the same problem. I researched the first special projekt and now i need to create the dark matter. I got a level 6 scientist with particel specialty in the phisics research exactly as asked but nothing happends. I dont get a reseach i cant do the next Special project and i also cant ask the curators for help since they dont have that option. Anyone found a solution yet?

I just had the same problem - all conditions fulfilled, the "trigger" command implied that all conditions for the tech were met, but it didn't show up in my research options nor in "techweights".

If you are not playing in ironman mode, you can sort of fix this using these console commands:

add_research_option = tech_dark_matter_generation
add_research_option = tech_dark_matter_container
add_research_option = tech_dark_matter_strategy

I found out what was causing the issue: another mod redefined the tech tier requirements, and since ACOT doesn't have its enigmatic tier anymore, it was easy to get stuck (not enough ACOT-themed techs in the tier, and I was avoiding techs by the other mod at that time for pool dilution reasons).

You just have to wait and be patient. The researched special project will stay there greyed out after you research it. You will then have to sit with your level 6 scientist till it shows up and it can take some time. That was the case for me anyways
