Hmm - someone has commented this code out. From play.c:

#if 0

    removed until gnubg/GoodDouble handles beavers and raccoons

    if ( fTutor && fTutorCube && !GiveAdvice( GoodDouble( TRUE, pmr )

Joern took this out in rev 1.145 (Aug 2nd). He may know if the problem
has been fixed and this simply has been overlooked or if it's still there.
