(13312895) NPE when creating a duplicate site with a Site ID greater than 40 characters
When creating duplicate sites, if you create a site with a Site ID greater than 40 characters, when you try and save the site, you will get an error indicating that the Site ID maximum length has been exceeded.

Workaround: It is recommended that you do not create sites with Sit IDs greater than 40 characters.

(13313881) Property updates may be lost in multi-tab Quick Edit dialogs
When creating duplicate sites, the code verifies if a property has been updated. In multi-tab environments, when the property is validated in one tab, the second tab will not recognize that the first tab has been updated and will over-write the new property data with the data from the repository.

Workaround: It is recommended that you do not create multiple tabs within the quick editing dialog.
