I working in a multiplayer construct game, my english its bad sorry if i not understand right your words, but that mean… i or everybody who want something like this multi-player or have collisions of spawned object in a multi-player environment try with other engine? Since Capsule/Character fail in the collision of the spawned actor/mesh.
I not understand why something that work in single player ok not work multiplayer and its a “intended result” 
Perhaps i not explain the problem right and your are looking to other thing? i can record a video.
