Inara has an update on the Aditi Inventory change. Aditi is the preview/beta grid. It is very problematic for now. For now the work around is to use a viewer in Aditi that does NOT share an inventory with the viewer you use for Agni (the main grid).
Using the same inventory cache for Aditi and Agni will create problems for you on both grids. See Inara’s article: SL project updates 16 13/1: Aditi inventory, invisiprims.
