Solver work reduced to 2 moves in the first step of LS. The first move is successful and the second one fails with corrupted score: {noformat} 2016-05-17 11:36:23,934 [main] INFO Solving started: time spent (79), best score (-1600), environment mode (NON_INTRUSIVE_FULL_ASSERT), random (JDK with seed 0). 2016-05-17 11:36:23,938 [main] TRACE Created cachedMoveList: size (25), moveSelector (Shuffling(Filtering(SwapMoveSelector(FromSolutionEntitySelector(SeatDesignation), FromSolutionEntitySelector(SeatDesignation))))). 2016-05-17 11:36:23,938 [main] TRACE Shuffled cachedMoveList with size (25) in moveSelector(Shuffling(Filtering(SwapMoveSelector(FromSolutionEntitySelector(SeatDesignation), FromSolutionEntitySelector(SeatDesignation))))). 2016-05-17 11:36:23,952 [main] TRACE Move index (18), score (-1600), accepted (true), move (Aaliyah {2.7} <-> Aubrey {2.5}).
