I found another report on this (https://bugs.mojang.com/browse/MC-17247), but it didn't include 14w06 a or b. I found this bug when I went back to a world I made in 14w04b, And after the villagers had stopped farming, they sped across the fenced-in farm. This is probably do to the villagers trying to get home, but ignoring their normal walking speed set by the game. When farming, they follow the walking speed, which, in my mind doesn't make any sense. Photo's & World below.

Villagers walk normally when farming, but speed around when not.

Is this still a concern in the current Minecraft version 14w11b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. - bot
