Text reverting to placeholder text when color changes

Hello, after talking to a Figma employees, we were assured that making a minor change such as color styles in the master/primitive component would not cause issues when publishing. Recently, we have seen 3 different components get reverted to placeholder text after simply changing the color of the text. This is very frustrating for our users and causing us to hesitate with publishing further. Is this a bug that has just come up?
