Use the official news page and Steam community hub as the starting points for update information. This wiki page is an update-check workflow, not a replacement for official patch notes.
Read the official announcement and patch notes
When a guide no longer matches your game, first identify the latest official announcement and any associated patch details. Note the update date and the systems it changes before troubleshooting an old setup.
Recheck affected guide topics
Updates can affect buildings, business requirements, products, employees, logistics, blueprints, and mods. Review only the guides connected to the changed system, then test in a non-critical save if the update is substantial.
Keep community evidence in its time period
Steam discussions and Reddit posts can be valuable, but their advice is tied to when they were written. Prefer recent posts that name the same version you are playing.
