[Creature And Spells] No Collision Check?

[Swarven]

I have vmaps and maps placed in my server. With the Collision enabled in world.conf

But players are able to cast spells through m2 and wmo. and Creatures run through m2 and wmo. Is this normal? how can this be fixed?

with vmaps they shouldnt be able to cast through m2 and wmos if you are not in there LoS. Creatures running through m2 and wmos are pathfinding issues and can be fixed using mmaps.
