Bug with luring boar? Or is this normal

This isn't a big issue but something quirky that I've picked up. Sometimes when I lure my second boar if there's still food left on boar 1 I'll task the lurer to gather food from boar 1 while the other vils shoot boar 2. The problem is if you task the vil to gather from boar 1 while boar 2 is still alive, he will just shoot boar 2 instead. I've lost a vil a couple of times this way as I task him the boar 1 on the way back to the TC but he just stops and fights boar 2 instead. Obviously this is a bad habit for boar luring but something I thought I'd mention to see if anyone else notices the same behaviour.
