Chunks Not Generating/Loading Correctly In Client & Servers (Major issue)

Whenever You Create Or EVEN Load A World In BOTH Singleplayer & Multiplayer Servers, You Get This Giant Void In the Middle Of Your World, It's Even Walkable, Animals/Mobs Spawn On It, The Chunks Are Like Missing...
It's Not A Resource Pack That's Doing It, I've Even Checked It In The Default Resource Pack... It's Getting annoying... And Even Worse, If You Quit The Game In The Middle Of Nowhere, & Then Load Up The World, MORE Chunks Are Missing, & They Happen Nearby, Too... It's Just Annoying!!! In Fact, It Got So Annoying That I Started Playing In Nothing Else Out Of All The 1.8 Snapshots, 14w21b, For My Servers... & Singleplayer, Too... This Has Happened Since 14w25b - 14w28b
