It is kind of embarrassing and spoils the immersion (no pun intended)
The other thing is that when you spawn atop your conning tower at the beginning of the game, you are in a slightly elevated position. It's not until you move forward beside the UZO, that you drop down into what is obviously your proper position.
A huge amount of problems have been solved thanks to TDW and many others. Who knows, fixing these silly bugs once and for all may lead to solving other problems.
Anyone?
