Event script did not retain applied changes on project save

so, yesterday I finished a screen with a submit button. I use the apply button and I save my projects profusely. I probably do it way too much. So, I finish the last touches to this script and savie it. I test everything and it all works. It is the end of the day, so I save one last time. I then close the designer and choose save & exit.

this morning, my script is back to where it started when I began working on it yesterday.

anyone have any ideas or experience this before? the ironic part is that my project script did retain its changes from yesterday.
