I see this exact statement quite often. The problem is that glass has a tendency to not break at the moment that it is stressed, but to sit and fester with a tiny little imperfection, then due to a slight provocation (such as a change in temperature overnight) completely let go. The damage may have been an unfortunate corner drop a month ago...
You may have seen it on car windshields... a tiny rock ding in the corner for many months, then one night when the temperature changes, bam, major crack across the entire window.
