I'm not sure if this has been reported recently or not but it needs to be brought up again and hopefully fixed
Animals that you are leading are notorious for NOT entering mine systems WITH you. It also happens on wagons/carts, you'll take a wagon into a mine and half of the horses on it will be above ground instead of in the mine. This is very irritating as I've seen people lose and have lost countless horses in pvp because the damn things didn't follow the into the mine.The best is when someones defending a deed and they take their wagon into a mine and all 4 horses stay above ground and you can archer their entire wagon to death
my irritation level with this is 10/10 atm
