The problem is that this is not a solution - only a partial workaround. The ‘Auto Face Forward On Attack’ setting is the new setting introduced to provide PC players with the ability to fight again, after removing that ability in chapter 3. Unchecking that box returns the player to ‘locked facing’ making turning during combat (even between strikes) not function properly.

I realise this is intended purely to help people, but presenting this as a solution gives Funcom the excuse to not actually fix it - leaving players forced to choose between whether they want their followers to be able to fight (and mount not to charge into combat) or if they want to be able to fight themselves. Personally I would like my followers not to be broken and also to be able to fight without getting locked facing the wrong way.
