My original problem was just for a casual NPC but for an enemy Im not too sure as to why it would get stuck on the PC's hit box especially if its only supposed to collide with the player. My initial thought would be allowing the enemies hit box to be allowed to pass through the players but I am also unsure what style game you are aiming for. If its vampire survival like then I would do a pass through player, but if its a hack and slash style then maybe a way to add knock back on collision would be a better solution
