If you are updating from v1.6.3, you may run into an error 'Cannot read property 'x' of undefined'. Please follow these steps to resolve:
1) Open Core Engine parameters in the Plugin Manager list.
2) Open the Hand Zone parameter, find the parameter called Targeting Card Card Offset.
3) Double click on Targeting Card Card Offset to open the parameter. And then hit OK and exit out to the game. It will have refreshed.
That's it. That's all you have to do to. Very annoying that RPG Maker insists on setting new structs to undefined when updating between plugin versions.
