While i was playing crysis demo 4th time in a row i found this beachcamp full of koreans and a small boat, it was on dry land and i decided to jump on.
i entered the boat and found myself on driverīs seat,changet place to a passenger one and back.
when i got out i had 4 hands holding 2 weapons and increased kickback.scheenshot shows the problem and the boat i was talking about.

cant upload screen, messed up this post but the nature of the bug is clear enough
