In Firefly, useing the Firefly Video Model to prompt edit a reel video, I've submitted the prompt twice and been charged 250 credits each time, but no new video has been produced.

I generated an image-to-video piece for 500 credits and then selected to edit the result with a prompt for 250 credits. Both times when I clicked Generate it deducted another 250 points, worked for a while, then stopped without displaying a new video. I’m afraid to try again because it’s just bleeding credits...
