You use another plugin? Like VS battle core?
I made the plugins to work with base RPG Maker MZ and all of my plugins are tested and works good, maybe is a compatibility error with another plugin
I going to check anyways when i come from work!
I deactivated all other plugins and was still getting the error. Thanks for checking! The error appears when you choose to Attack in combat (possibly other actions too)
I made some fixes please redownload again the plugin and test it out i hope the changes fixes your problem!
It's working now! Thanks for the quick fix :)
No problem! Thanks to you for use my plugins!
