[2.0.14] Deconstructing Landfill with buildings on top causes sound loop

[Kittingsl]

Basically used the deconstruction tool on landfill where i had buildings sitting on top already marked for deconstruction. once i marked the landfill the bots flew to the landfill and constantly played the deconstruct sound and animation while waiting for other bots to remove the buildings on top, instead of waiting with the deconstruction until the buildings have been removed
