This has probably already been asked, but I couldn't find it. It also may not even be a bug, but just a change in the fighting system. But anyways...
I've notice that many of my attack cancel themselves out just a second or two after I've selected the target. I can't find any real rhyme or reason to this. It just seems to happen at random points. Am I missing something?
Yes, you are. It happens when you ctrl-click before you can attack again. If you wait until after you can move, move items, ect then attack again it will stay locked on.
