[ BUG ] Researching patents pulls QL of prerequisites patent

EDIT: This has been identified as a bug. Please skip the below original post, I thought it was a normal function and was suggesting something to be done to improve the quality of life in the game.

Ok so first off I apologies if this was already posted. I tired to find something like this and I could not. 


So I was thinking about the research of patients and I really like the mechanic of progressing to unlock higher items like as an example from Metal to Magmium then to Vulcium. 


What confused me a bit was improving on the designs when finding higher QL materials. Having to re-research to unlock improvements makes sense. What does not is having to go all the way back though the whole chain. Like if I wanted to make an improved grav drive module, why do I have first improve my chemicals rockets? That's like going back to the first patent of the telephone and having to improve that to make the latest cell phone. You don't have to do that for mining right now and that makes sense. 

I'm suggesting that once you unlock the technology it should not be as hard to improve on it. 

Thoughts?
