Auto aim bug. Scenario:
You are fighting with guy1, and guy2 aggro's you, the main target remains guy1 (even the arrow points still at him). Auto aim attacks like go for the jugular target guy 1, as they should. But "manually" auto aimed attacks like punch with Shift are aiming at guy2, who is not your target. You need to cycle again after sbdy aggro's you to your correct target, otherwise you'll aim always for the newest guy who aggrod' you.
So.... pls fix
EDIT: Also, auto-aimed punch/left hook tend to miss a lot. Which is annoying
