Downloaded images not recognized until Codea is restarted

My project automatically downloads all the necessary images for it to run, however, the images are returning nil after successful downloads. I have verified that each image has in fact downloaded correctly and with the correct name. An error is occurring at the first instance of an image call. Here is my current project:

On first load, you will receive the error related to a nil image. After restarting Codea, the project will run correctly.

Post this to the issue tracker - see link at top, above

I have the same issue if I create a new tab from code. listProjectTabs() throws an error until restart. This seems to be with longer generated tabs.
