I will check them out. What happens is that the building is destroyed, but it doesn't disappear. Those buildings definitely should though. I will check it out.
I dont think it is the buildings .... I found that I have to constantly adjust the machine to allow the hydraulic hammer to continue hitting the building. There is definitely a sweet spot, but I set it up, leave it running, and that I come back and adjust ...... rinse, repeat.
Have also seen some buildigs that doesnt dissapear after it stops hammering. And some objects like the arc, and som veichles that cant be demolished or removed.
