Hello! I just purchased this plugin, but I'm having issues getting it to run; every time I launch my game I get this error; 

TypeError: Cannot read property 'skillId' of undefined.

I've tried turning off all other plugins and combing through this one, filling in the Skill ID's with different skills...I'm unsure of what else I can do. It works in the vanilla project, though, which is even more confusing. (Considering all of my plugins are off.) Would you happen to have any theories of what could be happening?  I'm using the MZ version, and both  beta and regular return the same error.

This is likely due to the plugin's parameters have some default skills setup in the Custom Skills section. You will either need to go through all of them to change the skill ID's to a skill that exists in your game's database, or just delete them all and slowly add skills as you develop your game.
