Heya,
i been running a test project to see how id be able to transfer the plugin to other projects and i've run into a issue.
to my knowledge it seems like both the card battle system and turn based are clashing with one another, perhaps i'm wrong, but as attached below, bugs indicate missing images/parameters that aren't set within the actual game files (default.png).
the only other plugin i'm using is MV3D, and i had run a test prior with the plugin below yours on the demo project file, combat worked just fine.
so i must be doing something incorrectly for the card battle system to not display/function properly.
appreciate the help!
