When trying to drag in stock items that were included in early beta versions (e.g.: USITT and Prolight 2019 venues), they do not appear in the model.
Explanation of Issue
If a show file was created in an early beta where those models were included in the library or if the default Augment3d model was created while those items existed, they continue to appear in the list displayed in the Library. The models were removed prior to the initial release of software and are not actually available on the device to insert so attempting to do so results in nothing happening.
Do not attempt to use objects from the stock library that were removed prior to the initial release of software in a new show file. This defect will be addressed in a future software release.
