DoubleX commented that his might have compatibility issues with varying scripts, since it's new I think it's still being tested.
I'm currently playing with it and it's notetags to see if it all runs smoothly and as instructed.
I'm wondering which script of mine you guys are talking about as I really have no idea about it. It seems that it's my unison item script, but I didn't remember or know the things you guys mentioned are related to that script at all XDDoubleX works fine with symphony. he post a video to prove that.
but you need to install his Yanfly Battle Engine compatibility fix.
