At first I got the exception: java.lang.IllegalStateException: The moveClass (class my.planner.solver.MoveGroupToPeriod)'s move (PROJECT Period GroupChange:{T= Inspect 55871.I#0 [4->4] Bart DE BIE IV XI} => (P5)  [i1]) probably has a corrupted undoMove (my.planner.solver.util.TaskChangeListMove@35e8df37). Or maybe there are corrupted score rules. ... I found out that I did not undo all changes that I made in the move. After fixing this, I now often get Score corruption as below. I checked and all changes are preceded with director.beforeVariableChanged(...) and followed by director.afterVariableChanged(...); What could cause this corruption? java.lang.IllegalStateException: Score corruption: the workingScore (-286hard/-30601soft) is not the uncorruptedScore (-286hard/-30401soft):   The workingMemory has 3 ConstraintOccurrence(s) in excess:     preferedRegion/NEGATIVE_SOFT:[{T= Inspect 115519.I#0 [8->8] Dirk JANSSENS IV V}, Johan LAMOTE, 99, V]=99     taskSpreading/NEGATIVE_HARD:[(P7) , 77]=100     preferedRegion/NEGATIVE_SOFT:[{T= Inspect 115519.I#1 [8->8] Erik VERHOEVEN TL V}, Dirk JANSSENS, 99, V]=99   The workingMemory has 6 ConstraintOccurrence(s) lacking:     preferedRegion/NEGATIVE_SOFT:[{T= Inspect 115519.I#0 [8->8] Dirk JANSSENS IV V}, Dirk JANSSENS, 99, V]=99     taskSpreading/NEGATIVE_HARD:[(P7) , 75]=36     preferedRegion/NEGATIVE_SOFT:[{T= Inspect 115519.I#1 [8->8] Erik VERHOEVEN TL V}, Erik VERHOEVEN, 99, V]=99     preferedRegion/NEGATIVE_SOFT:[{T= Inspect 4747.I#0 [10->10] Johan LAMOTE IV V}, Johan LAMOTE, 99, V]=99     taskSpreading/NEGATIVE_HARD:[(P8) , 74]=16     preferedRegion/NEGATIVE_SOFT:[{T= Inspect 4747.I#1 [10->10] Dirk JANSSENS TL V}, Dirk JANSSENS, 99, V]=99   Check the score rules who created those ConstraintOccurrences.
