Houdini crashes with an active octane license.
I start Houdini again and see a message that the license is taken. Obviously by the process that crashed.
I can't log out of my Octane account because in the new Houdini session Octane says I'm not logged in. It's some kind of vicious circle.
The only thing that helps is unlocking from account/subscriptions.php or writing to support. But it is very frustrating.
