Dang it, I thought I searched properly.
and another where the zombies make it across but very strangely, they spin allot and wander back and forth, they eventually make it across but not fast enough to fit in 10mb at my settings
i've uploaded a video of a villager not able to get away from a zombie and the zombie not chasing the villager when it got knocked onto the slabs.
but not walk on it? they are trying to jump up walls that have slabs on them and aren't walking over bridges made from them.
oh sorry first report
Oh, sorry about that. I thought I'd searched well enough to find if it was already posted. Yeah, that describes exactly what I reported here.
