Master Properties Bug
I have a character rig setup with Master Properties. The hands use a drop-down-menu control to switch between hand poses. If I try to add a new pose to the drop-down-menu, After Effects goes unresponsive for a few seconds, and then all of the keyframes are gone from all of the channels on that layer.

Thank you for the prompt reply. I'm glad that it's being addressed, as it's causing some major pipeline challenges for us.
Thank you for reporting this bug. This is a known issue with Dropdown Menus used as Master Properties. There is not a good workaround at this time, unfortunately, other than finalizing the Dropdown Menu items before keyframing any Master Property instances.
The team will be taking a look at this issue. Thank you for your patience and apologies for any frustrations this has caused.
