Hi,

either I am very blind or there is a mistake in the research for the D-He3 plasma cell. The combination of the needed Tech cards is not possible to research, because the Space Science Tech Card has to be researched in the Singularity Lab, while the other Tech Cards can only be processed in the normal and advanced lab.

Thanks in advance!

You should be able to research it in the singularity lab. Just checked, and it accepts the ones needed to research it (production, utility and optimization).

Okay, so there is probably a mistake in the research recipe, because it needs also automation, logistic and chemical (which can only be researched in the normal and advanced lab).

Doesn't happen to me, weird. Do you have any mods other than K2 and RFP? And what are your mod settings?

Yes, I have some other mods installed. I can give you a save file, if you want.

Either tell me which mods you have, or send me your mod-list.json. It's propably some kind of mod conflict.

Here are the mod-list and settings files.

That'll take some time to test which mod exactly is causing it, I'll reply when I find it. One more thing though, can you check on a new save if it's the same?

Of course, I'll do that!

It's the same - wrong tech cards needed.

I have tested it. I only activated K2 and RFP and started a new game...same issue.

Well that's weird. Try resetting the mod settings, see if anything changes?

Nope! RFP-Settings are standard... xD

It's the recipe from the K2 compatibility-patch.

Yeah, that's the vanilla recipe, it's changed in another file if K2 is loaded. No idea what's wrong, it's working just fine for me. What game version are you on?

Yesterday Factorio 1.1.5, today 1.1.6.
RFP 1.3.15

But in Vanilla I cannot find a D-He3 fuel cell in the research tree. So why a recipe for it?

PS: The screen was from the K2 compatibility-paches folder (data-final-fixes).

Found what the problem was, I had RTG installed when I was checking. It's fixed in 1.3.16.

Oh no...I thought about it, but didn't saw anything relevant in the RTG settings... Yes, I don't use RTG.

Now it's working and I was able to finish the last RFP research. xD

Many thanks for the fantastic help!
