Duplication of associations superclass contraints and more in TMCore07 SP3

EPiServer site with TMCore:
TMCore07 SP3 and TEM v2.3

During either the convertion from TMCore07 SP1 to SP3 or when I wanted to see what happend when I clicked the Generate Schema button in the Topic map editor, many of the associations got duplicated. In the tmcore database there is a stored prodecure called tm_RemoveDuplicates, that cleans this mess up. For a long time I was wondering if the duplications where supposed to be there, but running this script clarified everything.

USE [dbDatabasenavn]

GO

DECLARE     @return_value int

EXEC  @return_value = [dbo].[tm_RemoveDuplicates]

SELECT      'Return Value' = @return_value
