Looker won't let me commit because a file that doesn't exist, was supposedly deleted

[dan_bryan_alph]

As soon as I change a particular model file in my project (even adding one blank line to test), I'm unable to commit because Looker believes a different file (that never existed) was deleted.

When I look into the commit history there is nothing about this file existing or being deleted. Is there some gotcha I'm missing, or is this a straight-up bug?
