[MCPE-149683] Old type worlds are broken.

バージョン1.18.0のアップデートをした後のことです。
私の端末に保持されている、全ての古いタイプのワールド（有限ワールド）が破損しました。

ワールドの全周１０マス程度の空間が、加工する前の状態に戻ったかのように変化しました。また、そこにあった構造物は、空間が引き裂かれたかのようにぐちゃぐちゃの状態になっています。

地下も同様で、地下室として加工した空間もぐちゃぐちゃに破壊されています。

After updating 1.18.0，it happened.
All my Old Type Worlds(Finite World）were broken.

All the edges of the world was changed like a world that before making structures.
And my structures at that place were torn.

All structures in the basement were torn too.
