Collision help

Okay, after fiddling around with the collision settings some more I finally got the bomb to stop exploding as soon as it spawned. The problem though is that now the bomb doesn’t have any collision with solid objects, resulting in thrown bombs falling through the ground.

I don’t why happening as the collision settings for the bomb are set to block WorldStatic objects which I’m pretty sure solid objects fall under.

Static Mesh collision:

Sphere collision:

Bombs are able to interact with other objects such as enemies but not solid objects, so what’s the deal? Anyone have any ideas on what’s happening?
