Issue is similar to MC-36167

The first 5 screenshots were taken on my 1.8.1 vanilla SMP server, where I first discovered this issue. The last screenshot was taken in a 1.8.2-pre4 single player world, as I figured I'd check the latest dev version to see if the issue persists.

Steps to reproduce: Simply warp your way out to either 29,999,999 or -29,999,999 in the X and Z co-ordinates and place down a Redstone Torch.

The positioning seems to be incredibly random as evidenced by the 3rd screenshot. All other particle-emitting items (that I could remember) seem to work just fine.

Update: Just tested out the slime block's particles, when you land on it after a fall. They seem to suffer from the safe issue as evidenced by the newest screenshot.

Update 2: Seems all "falling" particles (when you land on the ground after a high jump) are mis-positioned. See newest screenshot.

Update 3: When fishing, the little water splash particles tend to emanate from the dirt. I even saw a few emanating from the air above a dirt block. The particles for when a fish is coming to your lure also tend to emanate from the dirt. I uploaded a screenshot but it may be hard to see the particles of the fish approaching my lure. Look in the area around my crosshairs, those blue dots are the particles.

Update 4: Rain is affected. I knew this and forgot to mention it. Rain doesn't fall from the sky out in the "far lands". I assume snow is also affected.

What this tells me is that any particles added after MC-36167 was fixed may suffer from improper positioning when occurring near the edge of the world.
