This was working until I did some updating in composer. I'm not entirely sure which package changed to cause this, but when I save my user entity now, I get this error:
Fatal error: Uncaught exception 'Doctrine\ORM\ORMException' with message
'Found entity of type __PHP_Incomplete_Class on association Mrss\Entity\User#college,
but expecting Mrss\Entity\College' in
[...]/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php on line 783
This seems to be related to this issue here: http://www.doctrine-project.org/jira/browse/DDC-1698
But I'm not sure how to fix it.
