Hehe, last game with out mod we were getting strong bottom bounce effects on the DICASS.
One blip you were there, the next you weren't! And then back again as a partial contact! And then again as a HUGE blip... and then you disapeared for good when you shows the buoy your tail.
Edit: I have to really congradulate SCS for making such solid sound engine with many many acoustical factors, the volumn was just set too high for all the pieces to work right!
