.theme_history missing

Hello guys.
I don’t remember when it started, but recently I notice the file ~/.theme_history disappears from my home directory. Then, terminal theme fallbacks to default, losing the theme I’d chosen. When I call th command, the file is created and it applies the “3024” theme, creating a new .theme_history
I’ve have created (touched? :wink:) the file twice this week. Sometimes it keeps between boots. Nothing serious, just curious.
