How are you? Thank you for your message.
Unfortunately, the Visustella suit is encrypted, so I have no way to manage or understand how its code is structured, which may lead to these kinds of incompatibilities. My plugin is designed to work with the default graphic resources of RPG Maker MZ. This situation happens to many developers, and that's why we are not comfortable with Visustella, as despite having a number of very useful and popular plugins, it becomes very difficult for us to adapt our plugins when the code is closed. I have tried to reach out many times regarding various plugins, and unfortunately, I have never received a response.
If there is anything else I can help you with, let me know.
