Create a mod with the following code in data.lua:

data.raw["gui-style"].default.new_style = {
    type = "frame_style",
    vertical_flow_style = {
        type = "vertical_flow_style",
        parent = "nonexistent_style"
    }
}

Game errors after loading sprites with the following message:

: изображение.png (27.54 KiB) Viewed 418 times

This is not the usual mod error, which looks like this if a non-nested style is improperly defined:

: изображение.png (30.01 KiB) Viewed 418 times

This happens in different styles defined inside other styles.

Thanks for the report. Looking into this - I don't see a way to make this work with the custom error logic. By the time the styles are being connected it has long passed the stage where minimal mode works.
