Scanning Website for Hummingbird Breaks Meteorslides

I expect changes in Hummingbird to break things, but I can't even scan the website without it breaking Meteorslides. Clearing the settings fixes it, but every time I scan it breaks again. Can't I scan and then manually start changing settings without the scan breaking things? I thought maybe running both W3TC and Hummingbird was causing it, but deactivating W3TC before scanning did not solve the problem.
