after exiting premiere MoGRT with responsive design-time won't store the retime
When you stretch the MoGRT with responsive design-time save and reopen the project it won't store the retimed data correctly instead the end animation would be cut off or lost somewhere.
Update to the Update!
Thanks to great information from users, we were able to nab what appeared to be the true root of the issue, a problem with the timing getting wiped from the project if no explicit interaction had been made with the timeline (like muting or unmuting a track).
If you head over to the Creative Cloud Desktop App and navigate to the Beta Apps section, you can download the Beta version of Premiere Pro (any version after 14.6 × 46) and the fix should be in!
Please let me know if the issues still occur for you, though. We want to put this one away for good, and are hopeful this time. Those zombie bugs are wild though!
The Reset Duration option is still available if needed as well.
