WinFormsのデザイナでコントロールを配置したりすると*.Designer.cs
というファイルに自動生成コードが記述されます。
この自動生成コードは変な癖があって、特にバージョン管理をしていると意図せず記述が変化して戸惑ってしまう事があります。

button4, button5, button6はPanel上に配置されています。
button13, button14, button15はtabPage2内のPanel上に配置されています。

PanelやTabPage内のメンバーの記述順序が降順になりました。下部にある宣言部の順序は変わりません。
又、何故かToolStripMenuItemのWidthが180から変化します。
#ToolStripMenuItemにイベントを作成して保存
更に、トップレベル以外のToolStripMenuItem.Clickメソッドをデザイナで作成した後に保存すると
// ...
//
// toolStripMenuItem2
//
this.toolStripMenuItem2.Name = "toolStripMenuItem2";
this.toolStripMenuItem2.Size = new System.Drawing.Size(180, 22);
this.toolStripMenuItem2.Text = "2";

this.toolStripMenuItem3.Size = new System.Drawing.Size(180, 22);
this.toolStripMenuItem3.Text = "3";
// ...
ToolStripMenuItemのWidthが180に戻ります。
ちなみにUserControlをプロジェクト内で作成してビルドした時も作成直後とその後のデザイナでの操作により変化します。
デザイナ上で最前面/最背面へ移動等の機能を使った場合にも変化します(これは本来の挙動であって癖ではないはず)。
又、デザイナを開いたままビルドすると、同じプロジェクトでビルドされるユーザー コントロールが含まれている場合、それらの順序も変化します(デザイナを閉じていると変化しない)。
#対処法
デザイナを使用してコントロールを操作したら、最後にFormの適当なイベントメソッドを作成・削除してから保存する。
ビルドする時にはデザイナ ウィンドウは閉じる。
他にも方法があるかもしれません。
