This happened when a glowing feral ghoul was gooified with a plasma gun. It probably also happens upon disintegration with a laser. In those cases, the engine disables the actor and places a goo blob/ash pile instead, so the actor is likely not loaded anymore when the OnDeath event tries to do animation-related stuff. A 3D check should fix it.
