@KamiOh - If you turn up the GFX quality you'll see those are tires which have a foothold where a character and items can stand on it. They have the same behavior as other platforms where projectiles sometimes get blocked depending where you are when you use a skill
I understand. However, as you can see, the arrows can go through the tires on the right side but not the left. It seems like a bug to me."
These aren't flat surfaces so one side might have a platform angle that prevents projectiles from going through
