Had a wild untamed horse in survival mode. Clicked on horse with empty hand. Nothing happened, could not get on horse to attempt to tame it at all. Attempted shut down game and retried. Still doesn't work. Attempted holding saddle in hand (not the usual way, but I tried), attempted changing game difficulty from peaceful to normal mode. None of these efforts worked. This does not appear to be the same issue others are currently having, maybe related though?
