Hello! If I have this problem " Corrupted undo move (Remove worker 52 from task 1.992) received from move (Assign worker 52 to task 1.992). Unequal lastCompletedStepScore (-6hard/0soft) and undoScore (-6hard/-11520soft)" It's for the error in a move implementation or in a score rule ? -- View this message in context: http://drools.46999.n3.nabble.com/Corruped-undo-move-tp3512364p3512364.html Sent from the Drools: User forum mailing list archive at Nabble.com.
