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

<div>I've implemented a very simple application using drools
planner consisting of a bunch of activities. My rule file is
very simple too and just counts the number of activities not
assigned. When I run Solver.solve(), I get the following error
