I'm playing with K2 and most BZ mods. The bakelite recipe from from Salt&Chlorine in tech Advanced Chemistry some how doesn't get unlocked. Factory Planner thinks it is unresearched and I can't select it in chemical plant. When I create a new Sandbox save with the same mods and request all tech unlocked it works in all chem plants.

Hi there. That's a bit of a strange issue. If it's a one-time thing you can use something like

/c game.player.force.recipes["bakelite-hcl"].enabled = true

to enable that one recipe.

I got it with the technologie reset command. I could not reproduce it in any way, really strange indeed.
