I got really confused when I saw this in-game, because I thought I had
fixed it already. I looked into it but apparently I just moved an
intercom and just didn't fix this in #77706? I literally have the double
newscaster in the pic, but I guess I just forgot to also fix that?? I'm
tagging this as no GBP because I cannot believe I missed this and it
should have been fixed in the first PR.

Anyways its gone now!

Say, aren't wallmounts supposed to fall down when not supported by a
tile...?
