Maybe you can make it so it adds some modded version of craft to prod tech?
cos currently any modded recpie fro concrete exept standart one and space age is not affected by prod tech
(i have recpies for concrete from Planet Pelagos+Muluna, Planet Tapatrion, Metal and Stars, Externed vanilla: refining, Planet Moshine, Planet Janus and Planet Corrundum+Muluna)
Also there is modded ver craft of Refined concrete from Janus

There should be a component from PlanetsLib that does it automatically.
In these days ill try to implement it

its being dealt with right now, couple of minutes and the patch will be out
if it works

yeah, it worked, thnx!
