flaky thanks for the report! I'll check that out, but I think I already know what is happening.
You can probably work around the issue by going inside of the settings table in the database and manually set default_route to the URL to the new homepage. For example if you replaced /tags with /all-tags, set /all-tags as the value for that setting.
The paths are likely hard-coded in the homepage switcher, but I can probably replace them. I'm assuming there's also some sort of problem that happens if you change the URL to a page while it's already set as homepage, I'll see what I can do about that. I might just reset the homepage if you edit its URL.
