Walking underwater

Hi @flouONEs

@ position 956.50, -3.07, 1264.61 we can wlok under water and boats sink.

I also (and some players) noticed a strange behavior with the cargo : when he left the harbor he turn on itseld and return to it.
After that, he turn again through all building of the harbor, like if there is nothing.
