Hi, yes the plugin does work, all of my plugins work. Alpha/beta plugins could be slightly buggier than my fully released plugins just because less people are using it so there might be some edge cases or compatibility problems not yet found, but I am usually quick to fix any bugs found.

Hi, you will need to provide the full error trace or I can't really know where the problem is coming from to help. You can find this by pressing F12 or F8 in game and then switching to the console tab at the top of the window that opens up. If this error occurs right as soon as the playtest starts before the title screen appears, then you need to set up the Fights parameter at the very top of this plugin's parameter list in the Plugin Manager.
