I experienced this many times, but I forgot to ask every time.
Here’s the scene.
I set my language to Traditional Chinese (using a mod of course), and I also enable a mod that is not localized.
When I first select the vault, it is localized.
Then I select the other item. It’s not localized of course.
But then, I select the vault again. It’s unlocalized!
And many other strings fall back to English too.
Can this be fixed?
