player can jump over cobblestone walls

Oh, I like this bug. Can confirm player can jump over walls, but Zombies and cows can't.

Chickens can also jump over, villagers can't.

Each animal can jump over cobblestone walls because of the bugs. Since 1.4 Mobs no longer trying to jump over walls, but they can.

Are you sure? Cows just looked lost when I tried to lead them out with wheat out of a cobblestone-fenced area.

hit them!

I agree it should be fixed (it is fixed for later versions)

I would like to know whether this was a bug or if Mojang did this on purpose? - how would i find out?

I just think it would have only broken if they did something to modify it

@Aden: There were fixes to walls in 1.4.3 (eg. MC-1332) so likely this issue was introduced while fixing some other aspect of wall behaviour.

ohhh - now it makes sense

if it is only players that can jump them i say mark it works as intended 😉

I checked another issue, it said it was a duplicate of this issue, and this onee has duplicates. god, why?
