I understand that you're experiencing errors during multi-turn conversations in Figma Make, where credits are being deducted even though the page is not being generated.
I can see that you've already submitted a support ticket regarding this issue. In the meantime, here are a few things you can try:
Wait for a short while and then try your prompt again.
If you have a file where you repeatedly see this error, try duplicating the file and start prompting again in the copy.
Occasionally a prompt will fail for an unknown reason and you may see "Something went wrong..." — if the issue still persists after trying the above, the specialist in your ticket will be best placed to help. For more details, please check Troubleshoot in Figma Make.
I'll add an internal note to your ticket (#1926020) to let the specialist handling your ticket know that you've also reached out here on the Forum, so hopefully they can prioritize your case. Please keep an eye on your ticket for updates, and feel free to continue the conversation there.
