First bug [game breaking];

While running on foot or on horse back, the rendering terrain in the distance fails to load correctly and thus causes an invisible, impassable barrier.

In some cases this will occur on two or three sides of the character. The effected size tends to range from 5x5 chunks wide to 20x20 chunks wide. The entities on the other side of the "invisible wall" become frozen and unreachable.

While in multiplayer, the glitch affects different players at different times in different places. Quote:"I can see you standing there, not moving but I can't get to you." This seems to occur most frequently in multiplayer games while on horseback but has happened multiple times on foot, and while alone.

Since I'm running the beta 1.9.0.2 I'm unable to have realms, thus I am always the host.

In addition, however rarely, the player will become stuck in the invisible wall and be vulnerable to all damage from outside sources. The only way I've found to fix a stuck character is to reload the map.

On occasion I've found it possible to maneuver my way around the dead-zone, and among returning to it later, have found that it doesn't occur in the same place every time. Please contact me if you have any information regarding even a temporary fix to this problem. 

Next, the second bug [this one won't be a whole story, haha sorry]:

I can't feed cows wheat to make them repopulate. It seems to occur when I leave the render distance. I have cows from 1.8.0.13 that have become suddenly infertile come the 1.9.0.2 update. This isn't to rough but you know.
