What happened to my first part of my flight N1943L

When I landed at ZZV and checked Flight Aware, the graphic was complete with full path.

Came home to book mark the page and I found I was stealthy for the first half of the flight. Granted, I was IMC for most of it, so couldn’t be seen visually and had to dodge a few thunder boomers in eastern OH, but ATC did see my mode C :smiley:
