I have the same problem. It apparently only occurs with Use Experimental Gameplay turned on, so far. I have only made 2 worlds with Experimental turned on and one off. I see a Pig, a Chicken, or Sheep with hearts coming out of it. Sometimes I can feed another of the same animal near the one with hearts some food and then they make a baby. But the animal that had the hearts coming out still has them after the baby comes out. But most times the animal won't take the food. They follow you while holding food but just don't eat it. The hearts appear to be random, most don't have hearts. I also tried to feed/tame a pair of ocelots. They took the food and displayed hearts but did not tame. They stayed Ocelots, not turn into cats.
I am using Windows 10 version 1.2.5 and am experiencing the same problem.
I play on my brothers PC Win10 Edition Realm and have not gotten the "Diamonds to you" achievement despite throwing diamonds between us several times on different occasions. He has received the achievement during this time but I have not. I don't know how that can happen.
The wheat field is located outside of my house. I removed a tree that was located in the field and the 5 blocks have started to grow again. It is just funny that I have been planting and harvesting several crops before this started to happen. So why all of a sudden does the tree become a problem? But at least I can grow them again. Thnx for the "light level" comment. I would never have thought to look at the tree as a problem. FYI, it was an Oak Tree. Maybe Dev needs to look at how leaves effect outside light levels.
Same problem here, animals (ie: sheep, cows, etc) would gather in a bunch near the enclosure wall. I would come back 5-10 minutes later and see leather laying on the ground and have less cows. I guess due to suffocation. Also they would sometimes appear outside of the enclosure when reloading the world or coming back after walking out of the area. I have also noticed an odd behavior with my penned sheep. They would try to jump and partially climb a ladder I had placed to get in and out of the enclosure. The ladder\blocks were 3 blocks high. My version is 0.14.3.
Sometimes when it "Freezes" I have to close the game and restart. That would be the time the game crashed on me. The game recovers from the freeze condition sometimes, maybe 50\50. Also I believe the freeze causes the game to not save the latest data so hence the lost terrain updates not being saved. The real puzzle is why then did the map upgrade save then😛
FYI, I did a quick search for Minecraft windows 10 edition beta XBox achievements and came up empty handed. So I created this new bug report. Sorry if it duplicated an earlier one.
I have just received a small update today for 1.9.2 and I too have the same problem after loading several worlds, overlapping music tracks. I need to restart Minecraft to correct the problem. As I can see on Google, this is not the first time for this bug.
I just tried to feed a Chicken in my Use Experimental Gameplay OFF world and the chicken followed me but would not eat the seed I had in my hand. So it seems that Use Experimental Gameplay ON or OFf has no effect on this bug.
