[Gameplay]-My champion locked onto the enemy fountain

When I was playing Lucian when I clicked to goto lane it locked onto the enemy fountain. I walked down mid lane right into malzahar. I tried clicking away and I tried to use abilities. I was able to use abilities but I instantly resumed going to the fountain. When I respawned it kept happening. After 5 deaths I thought maybe disconnecting then reconnecting would work. It did. By that time the damage had been done.
