Summary

Morning all. I've been trying to add Tomoaky's TMcard mini game plugin to my mv game and I've run into this error whenever I try to start the mini game. View attachment 145202 When looking at the console it looks like there's some kind of conflict with Yanflys battle bgm plugin, and I tried moving the plugins in front and behind one another while still running into the error.

I was able to reproduce the error in a new project that I'll link to here.

And here's a link to the plugin itself.

Do let me know if I could supply any additional information, and thanks in advance
