The old "Can't get depth under keel" problem

[letterboy1]

Has anything been discovered yet to fix this? So far my searches have only brought up the work-around where you save your game and then reload it, but sometimes this doesn't work for days on end. When I can't get a depth under keel reading it seems that alot of verbal response don't work either, like when you flood a tube or fire a torpedo - I can live without that, but I need my depth under keel reading.
