Please Fix

Downgrade your Factorio to 0.17.55.

If you just want to load the save, disable the mod.

Will you update it for Factorio 0.17.79 or have you stopped developing the mod?

The Factorio developers changed the base game so this mod no longer works. It exploited a "feature" in the rail system that the developers decided caused too many bugs to keep around.
