    An equation does not fit here. Is this line indented incorrectly?

The error occurs because of an '=' sign that's part of a previous equation. The problem isn't indentation, but rather a missing newline. The error could say something like "A group of equations must be on different lines, all indented the same amount." Worth thinking about.
