Accessed none trying to read property k2node customevent reload

I changed the Character from the Character Interaction pack and rigged him etc.
I dont know what happened but the reload animation doesnt play, instead the gun reloads itself without any character movement. I have tried way too many things, even with other characters or copying everything from the original character. After 4 days I could still not figure it out what the problem is. I hope someone can help…


Whatever is calling the BPI event EventWeaponReload is passing nothing as the reload anim.
