I know this is the wrong category, but I cannot open a bug report because i am not a Regular.
Basically, the animation editor does not show any keyframes or added parts on the timeline, however I can still edit the animation just fine.
Importing an animation only shows one part at a time, and I cannot change it.
Rebooting Roblox Studio does not fix the issue, and I forgot how to open an actual bug report (and even if I do I am pretty sure it will take like a week).
