I was able to get the plugins working after some troubleshooting, but for some reason, enemies don't seem to attack. Even when I manually end a turn, it just loops back to my turn. On top of this, my cards don't return to my hand, as if they were permanently removed even though they shouldn't be. I turned off all of the plugins I had that affected battles in some way, and I even copied the plugins directly from the sample projects, but I still get the bug. Even when cross-referencing my project with the example projects, I can't find any inconsistencies that would result in this happening.
I would really like to get this working, as I enjoy card-based battle systems far more than the standard turn-based ones, so I wanted to see if I could incorporate this into my current game project.
