My villagers in my first 2 villages have disappeared.  Ihave been playing in peaceful mode. I've traded with them, built and worked in these villages and the really big village Ihave been building a wall around. I have secured these villagers and created a 3rd iron gollem. They and all of the cats have disappeared.  This jas been lots of time and work and I really hope that you will fix this so that I can have my villagers back. 

 Village coordinates are (first village) -1565, 79, 237.

(Second Village) -1401, 63, -762.
