Hello,
Thank you for going through the trouble of uploading the save file - it really helps me out.
Now as for the issue - it turns out this isn't a bug, or even a mod conflict! Factorio unlocks the shortcut bar the first time you research construction robotics, but this is an unlock that applies universally, to every save, and to every new game you do after the first time you achieve it.
If you want to get around that, press ` (the tilde one) to open up the console and type /unlock-shortcut-bar
. Also, even if you don't do this, going through the blueprint library to get to these tools should work.
In the meantime, I'll look into adding a check for this to the mod to prevent confusion among anyone else that might try this mod without having the bar unlocked.
Thanks and good luck with your factory.
