Good news Jeremy.90!
I have located the cause of the delay, and fixed it in the latest release (v2.61). It was caused by accidentally calling a setup function once per line of an action sequence, rather than only once per skill. The function call was inside a loop that was going line by line in the skills notebox, so it was shifting the setup function into the Setup Action of all skills once per line in the note box, rather than the intended once per skill. The added delay would be almost impossible to notice on shorter action sequences, but with each line it'd increase a bit more, until you get to the point you noticed at 100+ lines.
It is corrected now, so feel free to re-download the plugin and see for yourself.
