What are common Swiss meringue mistakes?

Swiss meringue is incredibly stable, but it relies on a delicate thermal and chemical balance. The most common mistakes include not fully dissolving the sugar over the heat, fat contamination from egg yolks that prevents whipping, and temperature mismatches (too hot or too cold) if you are turning it into buttercream.
