New Discovery about radio masts

[Letum]

I was playing SHIII in a VIIC in 1940. I was Alt-tabbing to check tables and charts. After one Alt-tab I got a strange graphical error.
Only animated parts on the bridge where renders and they where renderd without textures.
The following parts where renderd:

The men of deck
Torped tubes
Most of the deck gun
The flack Gun
The Screws
The compass dial
The periscopes
The pointy radio mast (it goes down sevral feet below what you can see)
The big round radio mast (it also goes down sevral feet)

The Dev team obviously ment to animate them, but never did.
Its a shame I wasnt on a late war boat when the glitch happend, I may have seen more.
Ill try to recreate it.
