Certain project names result in errors and then disappear


I’ve tried creating jelly.glitch.me and toronto.glitch.me (static sites) a few times, and each time I get some sort of error. Most recently, I’ve been able to successfully name the projects, however the index.html live preview will not load at all (jelly) and I get “Project Not Found” (toronto) - and then they disappear from my projects page. This keeps happening! Before, the project names would revert to their initial names.
