I finally have a screenshot of that weird spacing issue I've encountered in some Sugarcube projects I've made. I'm able to consistently recreate it by refreshing the itch.io page for REVIVE. Closing the saves dialog and opening it again fixes the issue for at least that session until the page refreshes
The dialog clearly isn't wide enough for whatever reason in that screenshot. It's probably a DOM readiness issue related to reloading with the dialog open vs. opening after.
