What you're describing isn't expected behaviour, and it's also behaviour I'm not able to reproduce, having used the plugin extensively for my own projects. The whole array of skills in my projects can play out and selected skills don't play twice.
So : either you're using it wrong, you're not understanding how it works, or it's an indeed a bug.
I'm available to help you understand how it works, or to fix bugs if there indeed are.
I'd also like to know what steps I haven't mentionned in my documentation. Maybe the one where you need to specifically name it, but it's in the thread and it's also a default behaviour of the engine for all plugins, not only mine.
Sharing your experience with using it would allow me to improve documentation for parts that need it and clear issues for future users. I'd appreciate it. It might even result in a plugin you can use to make your project, which is the desired result.
I wrote that plugin, so for me the documentation is perfect and I can understand everything about using the plugin with it. It's obvious that for people who don't know programming and haven't written it it won't be perfect, and you can help:
Pointing me to what you don't understand is the best way to improve things, for me, you and everyone.
I reiterate about you writing me a PM with your issues so I can help you out without derailing this thread further.
