Two kinds of information
Announcements are short summaries attributed to official pages. Planning notes are our own questions and suggestions. They are not game formulas, tested strategies or official advice.
Missing information stays missing
We do not import Transport Fever 2 recipes into a Transport Fever 3 database. A numerical calculator needs a verified version, units and reproducible inputs before publication.
