Is there a known fix for the following exception:

This exception gets thrown periodically when pulling updates via Team Server. When it happens, the "Data Object" gets lost in the Settings for the sprite atlas. Then it begins creating new prefabs within the sprite collection folder. To fix, we keep having to go in and remove the extraneous prefab objects and then manually reattach the correct prefab to the Data object setting.
