Excellent observation! You are correct. Our server-side validation was set to filter out any duration above 596 hours and mark it as "expired". However, we have thoroughly reviewed this validation and have since removed it. This patch will be deployed to our server today, meaning a duration limit will no longer exist. We appreciate you bringing this to our attention. Thank you.

Okay - cool!
