Tested with different settings now but nothing seems to work. Spawn rule is “Always spawn, ignore collisions”. Also tested with “Don’t spawn” but then it spawns it anyways, so I guess it’s nothing with the collisions, thats wrong. I also noticed, if I just spawn the weapon actor, it spawns at the correct place (server and client) the “attach to” node makes things strange then. If I set the location rule to “keep world” instead of “snap to target”, it keeps moving the arrow to a wrong location. This also happens if I set all the collisions to no collision.
