Restored files have disappeared

Hey,

in a moment of spring cleaning, I accidentally deleted a folder I shouldn't had. NP, I recalled Creative Cloud's archiving function so headed to the website. I successfully found my deleted files and clicked the "restore" action. After confirming, the files disappeared from the archive list.

However, they never returned in my files list either. So now they are completely gone... No longer in the archive, and not in the files.

Any idea where they have gone, and how I can retrieve them??
