Reproduction steps: 1. Deploy Crystal Phoenix and Wandering Zombie. 2. Destroy Wandering Zombie so that you get its Headless version. 3. Kill the Phoenix and the Zombie. 4. Neither will drop the globe, while none of them state they drop none. @Sokolov Also do note I'm talking about HEADLESS Wandering Zombie, which is the one that should drop a globe.
Bump! This is still the case and seems to apply to Mindflayer Queen's Headless Version as well. @Sokolov
