Replicated actor spawns at 0,0,0 in case of collision

Hello, I have a really weird bug in my game. I think it’s easier to show it in a video but I’ll also try to explain it.

As you can see it works most of the times, it shoots the projectile where you aim. The actor spawns ~200 units in front of you but in case it collides with the world the client sees at it was spawned at 0,0,0 (as you could see on the server, it exploded right in front of him)
Any idea what kind of bug could it be? I’ll post some blueprint scripts if necessary but it has quite a lot of nodes associated with it.

Thanks in advance, Gabe

Also, in case of 2 clients and the server, the 2nd client doesn’t see the fireballs that are bugged but can see the normal ones.
