I tried to modify the current research with the combinator but it didn't work.
As a minimal example I used a constant combinator to add a technology as an input into the research automation combinator and checked the "modify research queue" box. However, nothing happens.
Also, the game crashes when I try to read out the research progress.
I would also love to see a blueprint which demonstrates the research control behaviour.
Agreed! I'm loving the ability to read in research progress and sciences, but I have not been able to modify the research queue at all. Would be great if there was a tutorial or blueprint on how to setup automated infinite researches.
