Commented Unassigned: discrepancy between fresh & updated SQL database [268]

I have noticed that the update file 1.6.327.0.SqlDataProvider.sql contains the following:

> CREATE NONCLUSTERED INDEX [IX_BugNet_IssueAttachments_DateCreated_IssueId]

however, the 'fresh' schema 'BugNet.Schema.SqlDataProvider.sql' does not include this index.

1) why is this missing?
2) what other discrepancies are there?
3) which version is correct?
Comments: I have attached an updated create script.
