Whenever I hit my attack key, my character just runs in circles around the creature and I can't make him stop doing this. People I know on steam have seen this, and experienced it as well. It's very strange and frustrating, especially the fact were some hostile enemy's that can hit you from far away can kill me very easily. Including, The Mactusk Family, Bishop, and Broken Bishop.
This bug happens to me most of the time, but sometimes I'm lucky and I am allowed to attack certain creatures. However, I can't really attack hounds, and the mounds that they hide in.
I played on a world before with my friends and we were doing a thing were one of us spawned in a boss and the other's attacked it. I was the attacker, and we did it for half and hour, nonstop attacking. Then we went on another fellow friends world, and whenever I attacked I just ran in circles around the enemy.
