This is what happens: View: https://www.youtube.com/watch?v=RZv_SdPw2H0 I have no idea how to fix this. It's a prop_dynamic parented to a func_tracktrain. I can give it a walk animation and start the train and it will work just fine, except for this bug which will stay. Properties: I've also tried "Disable Bone Followers" on/off and neither works. I don't even know what this does. Please tell me how to fix this.
