No worries! Glad it works now 🍻

@teddyzeenny turns out I had two clones of the Inspector checked out and one was stuck on an ancient commit. (╯°□°）╯︵ ┻━┻

Sorry for the trouble. I checked everything twice but did not realize that Tower points to a different directory than where I was building.

Works now.
