It's strange though: partially initialized solutions work fine in 
real-time planning use cases in cloud balance example etc.
Double check if you aren't calling afterEntityAdded() on the 
non-initialized entities too.
Also check that the construction heurstics run before the localSearch 
solver does (the order in which they are declared in the config xml 
matters).
