For context, I have made a new skill for the Spirit Glaive which I made by duplicating and modifying the Prelate's Charge TAE since that ash of war functioned similarly to how I wanted it to (playing an initial animation, then looping a second one until you let go of the button, then a release animation).
Everything works except for the FP consumption - for some reason only the very first instance of the WeaponArtFPConsumption event works. This seems to even transfer between hkt? I have attached some screenshots and a video which I thought would be relevant.
I am really stumped, I tried searching through server history and only found one other person who nobody replied to.
