VMAPS are an other problem. This Fix fix the summon on points, which are not in visible place.
Example: Last boss in halls of stones: Sjonnir
This boss summon adds on a specific point with Database table spell_target_position. But this points are not in visible of boss.
general fix in my eyes: Sometimes we have a special point out of visible, thats the fix
