no more anonymous rack views

The URL https://www.modulargrid.net/x/racks/view/ pointed to the last rack you had edited.
Users posted that link in the forum to show their rack which was confusing because it always shows the active rack of the current logged in user.

Now https://www.modulargrid.net/x/racks/view/ always redirects to the rack view with valid id, e.g.
www.modulargrid.net/x/racks/view/96349
