firefly bugs

Hello, I am experiencing some issues while generating images. Sometimes the system returns an error and does not create the image, but the credit is still deducted from my account and is not refunded. Because of these technical problems, my available credits keep decreasing unfairly.

Additionally, during busy hours, when I enter a prompt and click generate, the request does not activate immediately. I often need to click multiple times before it responds, which can cause several requests to be sent at once. As a result, multiple credits are deducted unnecessarily.

I would appreciate it if you could review this issue and help resolve the credit loss caused by these system problems.
