Migrated to Locations : Experiencing problems with serialized inventory - anybody else?

Migrated to Locations : Experiencing problems with serialized inventory - anybody else?

Hi, Just thought I'd reach out here to see if there are other users with difficulty since migrating to Locations (from using multi warehouse).

most of our errors seem to involve our serialized inventory:
      - cannot add items to package from sales order (error message says item doesn't belong to the warehouse, but the warehouse match)
      - cannot transfer serialized items to other branches (warehouses)

If anyone has any similar difficultly i'd be interested to hear how you overcame it.
I'm now into my 3rd week trying to get this resolved and support cannot seem to help.
Thanks
