I bought the plugin, however the version 1.4.5 of the action combat plugin isn't available on Itch.Io currently (only from 1.6.0) so I have the "Checkname is not Defined" error.
Yeah, you should always use the latest version of Action Combat. This DLC isn't updated to use the newest version but I'll do that this week. Don't forget to check news feed frequently or visit Discord and check News channel. :D
