Re: [rules-users] [planner] The presumed score is corrupted

A corrupted score normally indicates a problem with the Move implementation (or sometimes the score drl). Basically this happened: for a number of moves, it did the move, calculated the score and undo the move. One of those move was associated with a score -10hard/0soft, that was the best one. Now, it does that move (which is now called the "step") and when it calculates the score it's a different score 0hard/0soft. Try TRACE environment and see if it crashes sooner. Copy paste your Move implementation here. In Planner 5.4 there will be 2 out-of-the-box Move implementations to use, so writing Move's become optional.
