Hello,

I am running into a problem with Courier transfer... When I transfer from a site to a new, clean site, everything transfers fine (mostly). If however I attempt to transfer the whole site again or just a section of it then I get this exception:

NHibernate.NonUniqueObjectException

Usually this happens for a datatype. For example:

Umbraco.Courier.Core.Exceptions.ExtractionManagerException: There was a problem with extracting database information for the item:
Name:Approved Color | Id:0225af17-b302-49cb-9176-b9f35cab9c17 | Provider:Datatypes.
NHibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: -37, of entity: Umbraco.Courier.Persistence.V4.NHibernate.EntityClasses.UmbracoNode

This happens even for built in dataypes and even though I included them all in the <ignoredDataTypes> in the config, as: <add key="14">0225AF17-B302-49CB-9176-B9F35CAB9C17</add>

This is always breaking the transfer. Could you please advise me how to solve this issue?

Thank you
