When you remove some geoset that has geoset animations you need to delete the geoset animations too, or else will crash the game. When you remove the 'Hero glow' geoset you will get a window that says that some bones still references that geoset, same will say next with the geoset animations. Now when you go 'yes' for both of the windows you need to go to windows>geoset animations manager and you must click on every geoset animations, now you'll see that it has Geoset ID and under it some numbers, you need to find a geoset animations that don't have those numbers and says "none", than close the geoset animations window and delete that geoset animation with 'none' geoset. Hope you understood.
