Thanks for sending these through! This should help us troubleshoot what's going on.
- Plugin Manager looks good. We should be compatible with all the YEP, SRD and Kadokawa plugins you have listed. Unfamiliar with PDX plugins but it doesn't look like they interact with anything related to Card Game Combat.
- Core Engine params look good. Would you be able to send through a screencap of the Database page for Skill 2? It might be missing the Will End Turn passive which is necessary to pass the player party's turn and allow enemies to act in Battle (otherwise it always stays as the Player's Turn).
- It looks like a number of Card Types have unassigned values. This is not related to the errors you have reported, but please share a screencap of your Card Types list in the Card Types plugin parameters. If you copied the values over from the Demo Project to a fresh project, it is possible that many of them don't match which is why the console is giving a warning.
If you can provide the screencaps requested above, we can continue working towards figuring out what's going on with your project :)
