I've seen the video. If you are so kind, please send me all the "movement" files of the cats (Give me all the skins you have problems) So I can test them and also attach the configured JSON of the plugin. (Right click and copy the entire string of the parameters so i can analyze it)
At the moment I can't draw any conclusions, but I can think of 2 possible scenarios.
1) Something is configured wrong.
2) The crop size is affecting visibility.
