Updated my world from 19w07a to 19w08a, and in the latter, my pens of sheep and chickens are now empty, while the adjacent pens of cows and pigs have remained just fine.

WOW, so, I restarted, and they're there again, but as I try to feed the chickens they are all occupying the same space and are impassable. I bounce off of them every time I try to walk in their direction because they are a solid knot of overlapping chickens. Something is definitely wonk with their clipping!!
I returned to my animal pens after a long-distance mining trip to find all my animals missing. NOT just "invisible", as I could not feed/breed or strike them. I closed and reopened the world while standing closest to the chicken and sheep pens, and the pigs and cows came back but the chickens and the sheep remained missing.
Edited to add: This seems to apply to villagers too, although they do come back with a restart. I came across a desert village that appeared to be empty while carrying the "bad omen" effect, which did not activate. I closed and reopened the world again, and a number of villagers appeared in the village, along with a horde of desert zombies, and the raid activated.
ETA 2: Wild bunnies, a cow inside a village pen, and a tabby cat, all appeared in the village after the restart as well.
