What is wrong with my factory?

Hey,

since i rebuild my factory, the production line hangs on the step from “Fit Rollcage” to “Fit Hood” and i have no idea why. The “Rollcage” step can’t find the next slot, but why?

My save file is attached, i hope anyone can help me.

(The save folder is located her on Win10: %USERPROFILE%\Documents\My Games\productionline\savegames)

Your conveyor is in the wrong direction in multiple spots. The dark gray marks show what direction it is going in.

Thank you!
