"Same" font sizes, but they're not
In the most recent version of indesign, when I copy or duplicate a text box, the font size says it's the same, but it is about 2-3 points bigger. Even after eyedorpping the previous style, it doesn't change. I have to manually make a new text box, recreate the font details before copying and pasting it into the box.
This helped me when I copied text from one doc to another.
