Overlap event called only when in sight of a camera

Hi, I’m working on a multiplayer game. I have a following problem with the overlap events:

When 2 objects are overlapping and they are in sight of a server player (has authority true), the overlap events are beign fired on the server. That’s ok.

However when objects are overlapping but, they are in some other place of the map, so that the server player cannot see them, then overlap event are not generated on the server. Looks like some kind of oclussion is in place, but I couldn’t find any setting for that.

Could anyone please tell me how to generate overlap events for objects, even when they are not in sight of an authority player ?
