What's this third periscope thing?

Another idea could be completely delete it or make it really minor using a 3d editor.

With GR2 files you do not have IDs. The 'ID' is the name of the entry that through some algorithm gets converted to an ID.

It's not the 3rd periscope, it's the radio antennea. When TheBeast tried to lower it he probably didn't fully understand what I did to make it do what it does and thus messed it up.
