So for some reason, a browser reboot put my Worm tab back to Interlude 8b. As I hovered over the “next chapter” link to start working my way forward to the chapters I’m supposed to be at, I noticed that the url for Sentinel 9.1 says “cell-9-1” instead – I guess Arc 9 got renamed at some point? (The url for Sentinel 9.2 says “sentinel-9-2”, so it probably happened early.)
