I’ve had this happen to me lots too. I usually can fix it by going into my inventory then exiting it.
Im on an iPad Pro 10.5 and my render distance is limited to 6 or 8 randomly. Before 1.2 it went up to 22 without a stutter.
Yeah this sucks. I just bought a new iPad with a render distance of 24 chunks. After updating it was only 14, the next time I logged on it was 6. That is unbelievable! For multiplayer I understand. But for single player it should be whatever your device can handle.
I have been experiencing this same problem in 1.0.3. My iron golem farm keeps breaking because all of the villagers will explode out of their holding cells. But I'm unsure if it's actually on the chunk border where they escape. Because the chunky border is one block away from the holding cell. So I had to trap all of the villagers st the bottom in a fence.
When I say: "a block" I mean a 3x3 horizontal set of blocks.
I have reported a bug similar to this one but not the same. It was closed as a duplicate but it is a different bug. Please refer to: https://bugs.mojang.com/browse/MCCE-3945 for a detailed explanation of the same bug for MCPE.
Yes, I am having the same problem
I’ve been expirencing this since 1.6 released. It was fixed temporarily but it is back now. Can confirm that it affects 1.6.2
