Although irritating its not one of the massive show stopper bugs really.
Provided you reinstalled just clicking on the depth gauge where the current needle is will accomplish near enough the same thing for now.
If worried about hitting the button by accident, simply remove its keymap in commands.cfg
I suspect bug introduced because its trying to do some kind of unit conversion and overflowing/getting confused and dumping out.
The entire game is still based in metric and just converts through to imperial. Notice depth call outs are 33ft, 66ft, 101ft and so on - ie 10 METRE steps. Also depth under keel is "over 3280.1ft"....So that'll be 1000m then
Fairly sure this is whats causing the CTD bug.
