It's either me not understanding the secret button combination that I needed to press, or the craft button is totally unresponsive after a while. Whichever it is, it made me just a teensy bit annoyed. So please, can anyone clarify whether it was me doing something wrong, or do I need to restart every time it happens?

Thank you in advance.

I'm not sure but I'm in the same boat. Every once in a while the craft button will bring up the wrong panel. I save, restart, and it works again.
