[S7 Goliath] Demon in a wall and Automaton not properly dying

[Konrad22]

There is a demon on 17,8. That's a cave wall surrounded by cave walls. :/

When the Goliath dies, all Automaton of his side 'collaps' (disappear while making destroyed sound) and then every other chaos related unit just disappears. That's a problem, because there are some Automatons that are not on the Goliath side, who disappear instead of collapsing.

Kill him and see/hear how the orange Automaton just disappears instead of collapsing.
