Ok its springtime, and Im told to fortify a float of ice, but I cant pick up the chunks of ice from the water, the buddies do nothing, pressing B seemingly did not do the right thing either, can anyone drop a subtle hint please as to what Im supposed to do about it please? because Im stumped.

You start on a floating chunk of ice with a steering wheel. Face the steering wheel and get close enough and it will turn red, like with vehicles, you can then press your build button (default "b") to modify it or your interact button (default "e") to "drive" it.

Thanks man !! I was facing away from the wheel when I pressed B, I just looked down at the float itself.
