Problems with physics asset

Hey there you guys!

I’m having a problem with the physics asset of my NPC zombie. Basically when they are dead their is a strange and weird limb stretching happening and also they block the player from moving forwards. I have to jump to be able to start moving again! Is it something to do with blueprinting a blend pose? Does anyone know how to fix these errors please. I would be forever in your debt if you could clear up this matter for me!

Best wishes and kind regards, Glyn! =)

Do you disable the zombie’s collisions after he dies?
