I tried to do  a quick look to see if anyone else has posted about this issue and didn't see it. So, please forgive me if it has already been posted. 

I was messing around with frame animation and noticed that it randomly slows down.  Closing the program and reopening does not solve the issue.  It does not seem like it affects the physics based animation, only my hand drawn frame animation. I attached the video above to show what I mean. I am also using the steam version if that matters

I really love the program so far! I hope there is a fix to this 

EDIT: I just restarted my computer to see if it would reset the avatar to play at the normal speed. Nope! Really weird

For those who are using frame animation, it was a performance issue with my laptop. When it stops charging the frames dropped.

BUT NOW with the update the frame animations just won't work correctly at ALL. Even when it is plugged in and in performance mode. The frames of my tail animation are dropping  and it looks awful :( Is this something that will be fixed in the next update?
