Running the solver, I got this error
The constraintMatchTotal (...) could not remove constraintMatch (..) from its constraintMatchSet
Exception in thread "main" java.lang.IllegalStateException: The constraintMatchTotal (solver/Same employee - Keep parts together=[0]hard/[-12/0/0]soft) could not remove constraintMatch (solver/Same employee - Keep parts together/[[TaskPart [id=02-1,

It seems related with the following rule:
rule "Same employee - Keep parts together"
when
$tp : TaskPart (task.maxParts > 1, $e : employee, $t : task)
$parts : List( size > 1 ) from collect ( TaskPart ( task == $t, employee == $e ) )
exists TaskPart ( employee == $e,
task == $t,
previousTaskPartOrEmployee not memberOf $parts,
nextTaskPart not memberOf $parts )
then
scoreHolder.addSoftConstraintMatch(kcontext, 0, -1 );
end
Basically this rules try to check if there is an isolated task part.
