About lead and boat bugs

Hello. Well, as the title says, I've found the lead and boat bug. About the lead, the lead of the horse and the bone horse that I had connected to the fence with the lead from a far place had been broken. As for the boat, whenever I landed in the same position as the boat without moving, even if it was a dog, cat, or enemy mob, the boat would come to me. As for the boats, I feel that "getting down in the same position as the boat" has become a rule.
My guess is that there is some kind of bug in the "location information".
I don't mean to hurry you, but I'm really looking forward to a solution as soon as possible. Good luck.
