[r5718] 地下の電力線が撤去された時、tunnelbodenが撤去されない

[z9999+]

1.架線の撤去ツールで地下の電力線を撤去した場合に、tunnelbodenが撤去されない
2.公共事業で産業施設を撤去した場合に、tunnelbodenが撤去されない

1. When I remove underground powerline with 'Remove powerlines' tool, underground powerline will be removed, but tunnelboden will be remained.



2. When I remove a factory which is connected to underground transformer station, underground transformer station will be removed, but tunnelboden will be remained.
