Can't download creator.ionic.io app

I use ionic creator - but when I try to download the project I’m working on today - it causes a horoku error.

Either from the dashboard, or from inside the project, if I click the Download button, and then click “Download project ZIP” - it hangs for about 30 seconds “waiting for creator.ionic.io” in the browser status bar, and then:

Application error

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail

I can download some of my other apps - but not the “TeleMeetUp Client App”.

How do I troubleshoot this further?

You never received a reply on this? I’ve had this problem on and off, it’s very irritating. After I submitted a ticket, I received an e-mail telling me to come here, yet they don’t appear to visit these either. The amount of support for creator is baffling…
