Zip file is empty!

Hi all! I’ve been using Easel for awhile… so easy to use! I am having an issue with downloading a zip file of a design… the zip has nothing in it! What’s strange is that it worked previously with this design and I’ve made no changes to the design. Other projects I’ve done still produce good zip files. The simulation works, as does generation of gcode within Easel. No idea what’s going on!!
