Graphic bug when bumping into each other

SUGGESTED BY (Elise): During a weekly dinghy race, we bumped into each other, we created a graphic bug where the whole map was slanted in regard to water level.
At the boat position, everything was fine (buoys, speed areas...) but on one side, they were in the air, and on the other side, they were underwater.
Which made it very complicated to tell where we were going.
