Hello, I can't find the Module inserter planner to construct after the new blueprint changes. How do I get the planner now?

Do you have PickerExtended installed? If so, there is a mod option to hide planners (under Options - Mods - Startup). If that is selected you can get it by pressing Ctrl + Q repeatedly. Or disable the option to make it craftable once construction robots have been researched

Or press Shift+B to bring up the planners menu and select it directly

Way to many hotkeys in your mod for me to know them all :D
