I have Trac and Site Version 2010.4.446. I was merging a couple of enterprises by creating a new field name and enterprise name for each year and importing the boundries from the two old names to create the new boundry. Then I moved all jobs to the new enterprise name, and merged the jobs there, and was deleting the two old enterprise names from their respective fields. I was doing this for several years of enterprises and it worked great except for one year. It will let me retire the enterprises but not delete them. It says it is used in a task and can't be deleted, but all the jobs are gone from under the enterprise. What's going on?
