I recently moved my mastodon public/system directory to a different storage and, since that new storage is kinda slow I just decided to delete the public/system/cache directory. Turns out that also deleted the emoji.
Now, can I just delete the emoji in the administration interface, and whenever my instance will encounter the same emoji again it will show up in the admin interface again? Or will the emoji be blacklisted in my instance after being deleted from the admin interface, and I would never be able to add it again?
Can I alternatively trigger a redownload of all emoji images?
