Hit event not triggering on physics actor

ive been trying for some time to make my destructible be destroyed by my projectile. I found that switching the projectiles collision type to physics actor, and turning on simulate physics did the trick. However, now when i shoot my enemy characters, the hit events in them are not triggering. I cant simulate physics on them becuase that seems to make them fall through the floor, or bounce all over the room. Why are the event hits not triggering on my enemy characters after changing the projectiles collision to physics actor?

I believe you have to enable physics in order to get physics triggering.

That said if you have a problem with stuff moving you can lock the actor on axis XYZ.
