Hello my Darth Maul and Magnaguard has suddenly corrupted animations.And Darth Maul´s combo didn´t make damage.
I made a video because I can´t explain this.
Can somebody help me ?

A similar thing happened to me. Did you make any changes to the .combo file? That's is where your problem comes from.

No I didn't but can you tell me how you fixed it then?

I didn't fix it when it happened to me. But I knew it was from me editing the combo.

I made a completly new CIS side but Darth Maul is still broken ( I used the vanilla cis side from the assets folder)
EDIT :

When I remove the Magnaguard with electrostaff it works.But I don´t want to remove the Magnaguard.
Can somebody help me?

Try munging a brand new animation for the Magnaguard using this tutorial.

THANK YOU!!!!!!!!
