Fixing lost progress on heatmap

Hello, does anyone know how you can fix progress that was lost and is now not reflected on your heatmap? I distinctly remember completing a step yesterday and hitting submit your code to save it, but when I checked back today, it was not saved and it shows me as earning zero points yesterday. I know its not all that important as I am still getting work done, but something about losing my streak makes me feel a little disappointed as I have worked hard to at the very least do 1 step a day.
