Villager path finding

Villagers seem unable to open doors and so suffer from broken pathfinding, i created my own village from the shell of an abandoned one only to discover that my cured villagers can't open the doors in their houses to breed/socalise. if the doors are removed they follow their schedule as. i've witnessed villagers loose and then reclaim beds over and over again, standing as close to the beds as possible outside the house, but being unable to reach them due to the door blocking their path
