Regenerate thumbnails on local posts

Hi everyone. I was doing some maintenance on my server and accidentally nuked my pictrs folder (the one thing I didn’t backup…).

I can re-upload the photos and community icons I had added, but is there a way to get the server to generate the thumbnail on existing local posts?

Thumbnails from remote instances are working fine but I can’t get the local thumbnails to regenerate.

Any help is appreciated. Thanks!
