Hi!

Everything is ready to research the Foundry, but I already crafted 100 tungsten carbide in an 'Assembling machine 2'. Crafting another 50 won't matter. While writing this I reloaded my first trip to Vulcanus savegame and started over. Doesn't make a difference. So sad.

Any thoughts?

In your save, this technology has unsatisfied prerequisite: you have not researched "Calcite processing" which is researched by mining a calcite.

After 2500 hours played I cannot believe I made this rookie mistake! Just hilarious!

Thank you!
