Do you have binoculars? You will see blue butterfly in your bedroom while looking out window. Repair binoculars (go to mall) and look out the same window.
I have found a bug where general storage (any category) have turned to 0. Even when you (or bot) put new stuff in them they turned 1 to 0 instantly. But somehow they are there (I think), because one bot was accessing from them. I don't have old saves so I can't check how exactly it occurred.
