Hey Accatosh, i know it's almost a month since the last reply but maybe you still struggle with those plugins. I had exactly the same issue like you.
You need to place the Summon Core Plugin BELOW every other Plugin from Yanfly. After that it works just fine.
Hope it will help you or you found a way to solve this issue already.
So the overhaul on my project has been going great, I like this version of the project a lot more. It's more contained and less overly ambitious for what I can achieve given my constraints on time, money, and skills in advanced programming. I'm going to wait till my project is mostly finished to begin working UI polish again. I'm going to learn how to use LUNA MV to polish the project.
