What happened: I was leading a horse that I intended to kill, when I selected "attack's -> target", the combat screen popped up and my character promptly started fighting the horse WHILE the horse was still being led.
What I expected to happen: In the past, we've been unable to hit livestock that we were leading until we stopped leading it.
Steps to produce it: Lead an animal and then "attack -> target" it and wait. The combat screen pops up and you start parrying back and forth with the animal. I used a horse and a ram.
When I asked ingame if this was intended or simply an update that I missed the announcement for, it was suggested I put in a bug report. I do see in the update that there was a change made to leading when using "Charm Animal", but it did not mention the ability to now kill led animals. Not sure if it matters but I'm on Harmony so PVE server.
