I am merging two different prototypes into a single XD file. In copying artboards (some include components) from one XD file into the other I think I have broken some of the components (a red icon link? icon appears in the top right corner).
I did this using simple copy & paste. Is there a different approach I should be taking to avoid breaking the components? I did "make local component" and the red icon went away, but I truly don't understand what happened.
