dimitrisnik24, what you wrote doesn't match with an IRN description (quoted below). Is it a sort of a bug ?
This network allows communication of scientists, working in research laboratories on different planets. Each new level allows you to attach to the network an additional laboratory (laboratories of senior levels are join primarily). Of all networked laboratories in each study involved only those who have enough level for this study. Speed of the research increases and corresponds to the sum of lab’s levels involved in this research. IRN also allows easier combining of debris recycle methods, increasing recycle speed by 10% with each level.
