I've seen a SwC (Synchronize with Central) delete elements when Purge Unused indescriminately by another person on the team. In this case people were working in their local file, adding walls. Another person used Purge Unused and then SwC. This stored the fact that wall types that had not been used yet, as far as the Central File was aware, were deleted. When the other users used SwC their walls were deleted. Revit didn't reestablish the walls and types and the walls, it deleted the walls and types first...which eliminate the possibility that the other users walls could exist. Tricky and not a desirable outcome.
