tweens making certain objects go crazy?
Hello, a few months ago i finished my first flash video with adobe animate cc, it seemed like i had gotten the hang of it but now that I am working on my 2nd flash everything seems to be going crazy! When i try to make a simple tween for certain objects they just go crazy instead of moving like they did for my first film. Its hard to describe how in words so i'm attatching a few screen caps to demonstrate. The neck of one of my characters should tilt and move sideways a bit but instead its shrinking then moving straight down before it randomly pops into the correct position of keyframe 2. This seems to be happening with a lot of my tweens in this film and i don't know why. Please help, I'm pulling my hair out trying to figure out why the operating rules seem to have messed up.
