Using the FAF hotkeys, Factory Repeat Build will not work. By the default FAF Presets, the hotkey is "Z". That doesn't work, and it doesn't matter what button I change it to, that doesn't work either.
It's strange because this is the only hotkey in the game that won't work, all the other hotkeys work just fine.
It looks like I'm not the first person to experience this bug either. Please help.
