Ok this might be something weird with languages and me not able to test for it effectively. If possible, can you send me a link to the project I can download so I can test it? It's a good test since it's in Chinese and I don't normally have the option to test with such a project.
Send the link to admin@psychronic.com
I don't expect project to be sent in an email (file size limit is way too low for an email attachment), send a link though to admin@psychronic.com (or I'm on discord too) to allow me to download the project, I wont use it in any other way than to just figure out the problem and fix it. When it's in a completely different language, the app will look at it differently, and if I can just see the project files directly, it will make fixing it much faster. I'm not able to change the language to another language on MZ other than English for my version, so this will help me solve it a lot faster for you if you can do that. Thank you!
I have uploaded the project; I'm not sure if you can download it, but feel free to modify and publish it as you wish. I hope this helps with your Chinese-language engine development.
