Yeah also having this issue. Admins haven't posted here since the middle of March so it might be a while until these bugs get fixed.

>>3669It's a problem with one of the blocklists your adblocker is using (probably easylist). If you disable your adblocker and try to favorite it, you'll notice that it works. You can report this on the block list issue tracker to get it fixed, probably.

Can confirm, temporarily disabling adblock lets me favorite artists with dashes in their name just fine.
