There was this guy on a jet pack behind some signs and I couldn’t hit him but when he moved then I could
That can be so annoying!
This happens with doors too.
I’m pretty sure this works as intended because when you are the owner of the sign/an admin, you can modify the sign, but not remove the backwall behind it. If you aren’t the owner however, you can’t remove or modify the sign, only go to the area. That’s why this occurs.
I think it’s just the layering of the object.When you tap on it,it will interact with the outermost object.In this case the signs are layered on top of the player and when you tap it,the game thinks you wants to edit the sign,but you are not an admin or sign owner so nothing will happen.
It is specially for pvp
