This mod revisits the early game of Factorio and pushes the electrification a bit further back by extending the Burner-Stage and inserting a new stage: Steam-Stage (buildings will be powered by steam).
It looks like an update to Concrete since I started my Phasma map added the Sinkhole. (I may be misunderstanding when it was first added.) Unfortunately, old maps which updated the mod don't have that recipe added. Would you create a migration which adds it?
