I edit videos. When I'm done, I upload the finished video to one Box directory, then upload the project directory to a sibling Box directory. The finished video is 8 to 15 megabytes. The project directory has 2 files totaling about 100 megabytes.

When I try to upload the project directory, it often just doesn't enter the upload queue after selecting it for upload from the modal upload window. I can do this multiple times and it doesn't upload. After reloading the page, then it will upload like normal.

This doesn't interrupt my workflow at all, but it might be a symptom of a bug. However I can't reproduce it with small files and an analogous directory tree.
