Hey @Spot technology — thanks for flagging this, and I'm sorry to hear you're down to 3 of the 4 that should be in your team project.
I was able to locate the file link, so I've opened a case and passed it to our Customer Support team to investigate on the account directly. Your case number is: 2033479.
One thing that'll help them match it up faster — reply on the case with the email address tied to your Figma account with the requested information.
Also worth a quick check in the meantime: Open your Drafts, go to the Deleted tab, and set the Created by filter to Anyone instead of you. Files a teammate deleted often surface there, and you can restore them yourself from that view. Full steps: Delete and restore files.
I'll keep an eye out for your reply.
