I tried pushing your plugin up and then the Picture Choices were working but then not your plugin (The code would appear before the text and it wouldn't hide the choices)
I could send you the Visustella's plugin to assist with compatibility, maybe?
Yeah, contact me on discord (winthorp) or mail winterdreamgamecreator@gmail.com and I see if I can make them work. By the behaviour when moving up or down it looks like they are both trying to use the same RMMZ function
